GMC Headlight Upgrade
 

I just purchased some headlight upgrades to the 67 GMC and couldn’t be more impressed. The headlight is glass and not cheap plastic. The bulbs really lit up my view. Overall, the update didn’t make the GMC look too modern or cheesy. It blended in nice with the grill and kept the overall old look. Here is what I ordered on Amazon

Nokya H5006 $89.95 pair
Lasfit 9007/HB5 6000k $36.99 pair

**couldnt post photos because I was missing a security token...huh***

Need pics asap

Re: GMC Headlight Upgrade
 

Did you buy two pairs of each? I'm curious to see how it looks/works with the GMC headlights/highbeams...

Re: GMC Headlight Upgrade
 

Hope this works

Re: GMC Headlight Upgrade
 

Headlights

Re: GMC Headlight Upgrade
 

Yes, bought two pairs. Best part was plug and play.

Re: GMC Headlight Upgrade
 

Excellent! I love the way they still look like the original. Do the high beams work as high beams or are they just extra headlights with this setup?

Re: GMC Headlight Upgrade
 

Works with the factory high beam floor switch.

Re: GMC Headlight Upgrade
 

This is great... I think I know what my next upgrade will be! Thanks for posting!

Re: GMC Headlight Upgrade
 

This looks pretty effing cool. Definitely looking into doing this on my 72. Awesome!

Re: GMC Headlight Upgrade
 

Sorry I'm asking so many questions...
I noticed that the bulb model for high beams is H5006 and low beams is H5001 (or maybe the other way around). I don't know if there's any real difference, but do the LED lights you installed in place of your high beams still work as well as or better than they did when you had your old high beams on?

Re: GMC Headlight Upgrade
 

When I get home, I’ll tell you which bulb is which and take a picture of the lights aimed down the street. That way you can see the difference between low and high beam and how much of the street gets lit up. To put things into perspective, the 67 is bagged and I still had several people flash their high beams at me thinking I had my high beams on. But I only had the low beams on.

When you’re asking your question, I think you’re looking at the factory bulb and comparing it to this set up. That’s apples to oranges. The factory is a headlamp and bulb as one. This set up is a separate headlamp and bulb, so two pieces. Think of this set up like a new car where you replace just the bulb and not the headlamp...aka housing. Does that make sense???

Re: GMC Headlight Upgrade
 

So I usually don't do aftermarket headlights but these are cool so you have to buy 4 of the sealed headlight bulbs and then buy 4 of just the led headlamp bulbs to use in the new sealed beam or am I totally missing what you have to buy here sorry in advance if that's the case.thanls

Re: GMC Headlight Upgrade
 

Since these are sold in pairs, you would do a purchase with a quantity of 2. This is for both the headlights and bulbs.

89.95 x 2 = $179.90

36.99 x 2 = $73.98

Total = $253.88

Re: GMC Headlight Upgrade
 

Keep in mind that these are LED bulbs. If you want a different kind of bulb, you have choices. Just look at the 9007 series bulbs.

Re: GMC Headlight Upgrade
 

Ok I was pretty sure that's what you did but wanted to be sure before buying wrong stuff thank you for your help they look great. It looked like in the Amazon picture like the light housing is the part that comes with the pig tail plug and play wire is that correct.

Re: GMC Headlight Upgrade
 

When you look at this picture, you can see the factory harness clip. The red/black/white harness comes with the housing (headlamp). The blue stainless piece comes with the bulb.

Re: GMC Headlight Upgrade
 

Ok yes that's exactly what I was picturing just didn't want to be wrong and have alot of unusable stuff thank you so much for the great explenation

Re: GMC Headlight Upgrade
 

I tried another set of plug and play LED lamps last year but they just didn't fit the buckets. Very cool to see another option, thanks for posting!

Re: GMC Headlight Upgrade
 

Those sure make a difference.

Re: GMC Headlight Upgrade
 

Looks really good compared to the dull yellow. For the bulbs, you suggest a Hi/Low bulb, but wouldn't you just need a pair of low beam and a pair of hi for the GMC?
I'm seriously considering this as the my next upgrade.

Re: GMC Headlight Upgrade
 

The outer lamps are both high and low beam... the inner lamps are high beam only.

So on low beam, just the two outer lamps light up. On high beam, are four are illuminated.

Re: GMC Headlight Upgrade
 

The LED bulbs are hi/lo in one bulb. So I have 4 identical bulbs. The way the bulbs are designed, there are two led strips. One strip is for lo and one is for hi. Even though both strips are flat on the surface, the hi beam strip projects the light at a higher angle than the lo beam.

When hi beam is on, yes all 4 lights are on. You can manipulate the wiring to have the outer bulbs off on hi beam. On my 1997 Chevy Silverado, the outer lamp is on for lo beam. When I switch to hi beam, the outer lamps go off. That’s how Chevy designed it.

Re: GMC Headlight Upgrade
 

Stock is separate wires for high/low beams on a GMC. Low beams on the outside and high on the inside. When you hit your floor switch, it just provides additional power to the inner set.

So I'll try to phrase this more clearly. If your stock system has only 1 circuit for the outer lights, and one for the inner bulbs, why use a dual filament (or dual LED strip) bulb? When you turn you highbeams on, it doesn't add power to a 3rd wire on the outer bulbs, like a Chevy. It only gives power to the inner lights.

So I could certainly see this working as expected (power the outer low beam LED with lights ON. Power the high beam LED on the inner bulbs when highbeam switch is on), but I don't see why a dual H/L bulb is needed.

...unless you want to have all 4 LED strips active with high beams, you could wire it up that way. I'm probably overthinking this :mm:

Re: GMC Headlight Upgrade
 

I had the same thought. You're not alone!

Re: GMC Headlight Upgrade
 

You’re right, you could do the following:

LASFIT 9005 - Hi beam bulb
Amazon price - $49.99

LASFIT 9006 - Lo beam bulb
Amazon price - $49.99

LASFIT 9007 - Dual beam bulb
Amazon price - $56.99

These are current Amazon prices. I bought the dual beam when they were on sale. Shop around on Amazon or wherever because you may find a cheaper price.

Re: GMC Headlight Upgrade
 

These bulbs should probably only be used in projector housings, not the reflector housings that you are using. I know that they say that they are halogen replacements, but this is wrong.

The Halogen bulbs that go in reflector housings usually have a coating on the end of them so that the light is directed toward the back of the housing and reflected out of the housing in the correct pattern, so as not to blind those in the oncoming lanes.

The projector housings have a lens in them that takes the light going forward (like from these bulbs or from HIDS) and then provides a cutoff so that the light only goes from the horizontal and down, and side to side. You will see a crisp horizontal line of the light.

Otherwise, you are sending light everywhere and into the eyes of oncoming drivers!

Re: GMC Headlight Upgrade
 

Do you have a housing in mind that would work with these lights?

Re: GMC Headlight Upgrade
 

No, I did the halogen upgrade with relays when I restored my truck and it was a significant improvement over sealed beam. The only thing that the LED does is give you options for color temperature (bluish light) and reduced power consumption.

I did a lot of research when I updated from halogen to HID on my VW, but already had projector housings in that car from the factory.

Re: GMC Headlight Upgrade
 

If the light pattern is what concerns some of you, they do have LED bulbs with the top cap to reduce the scattered light effect. But it’ll cost you a pretty penny.

There are mods you can do to any LED bulb without the cap to reduce the scattered effect in a reflector housing.

I have the relayed light setup in my 1997 Silverado and I will tell you that trying to compare LEDs to this type of setup is not a direct comparison. LED setups are for some and not for all.

Re: GMC Headlight Upgrade
 

I ordered lenses from a site called Daniel Stern or something like that. The lenses were approved by the European authority but not the DOT. The lenses were made with a sharp cutoff in the glass so that the light was directed properly and looked stock. I’ll see what I can find and post a link. I did this along with the relay upgrade and the difference was huge.

Here is a link to the website. It is pretty informative:

Here is the headlamp I used:

Re: GMC Headlight Upgrade
 

Went through this myself. I ended up going with halogen Hella E-code (european standard) low beams (low/high) and high beams (high only), after tossing around a bunch of ideas. I went with halogens because I wanted a stock look.

I can't comment on the Cibie's posted above, but I believe the Hella stuff is comparable, but may not be quite as good. The Hella beam pattern has a very sharp cut-off, dead spot for oncoming vehicles, and good ditch illumination. The high beams are very bright and have good throw distance.

I can post pictures of how the Hella's look and illuminate if anyone is interested.

Re: GMC Headlight Upgrade
 

I'd be interested in seeing that!

Re: GMC Headlight Upgrade
 

First image: left beam is Hella replacement, right is standard
Second: beam pattern on a building
Third: Hella low and high beam installed

Next time I'm out at night, I take a couple pictures down the road comparing the difference between low and high beam.

Re: GMC Headlight Upgrade
 

Been installing Hellas since the 70’s....:metal:

Re: GMC Headlight Upgrade
 

Those look really good. I'd like to see those pictures. Thanks!

Re: GMC Headlight Upgrade
 

Those are hands down some of the finest headlamps available. Hellas are good lamps, easier to find and cheaper than Cibies but Cibies have a better controlled light pattern, especially on high beam. More light on the road, less light in the trees than Hellas. If you've never had E-codes, either brand will be a noticeable improvement over sealed beams. But I think most people would prefer Cibies, even at their higher price.

Re: GMC Headlight Upgrade
 

First picture is the low beam
Second picture is the high beam

The red dot in the middle of the picture was a windshield reflection of an interior light.

Both pictures are taken with the same shutter speed, aperature and iso to avoid any adjustment made by the camera. The brightness of the near areas in the low beam picture sort of wash out what you can see at a slightly longer distance, but it is still an accurate representation of the beam pattern and throw distance.
