Headlights

[hessian18]

I recently wired up two 30amp relays for my Hi/Low beams.

Before the relays I was running sylvania xtravision in the low-beams. They functioned perfect. I recently went to switch back to my sylvania Silverstars. ( they are noticably brighter) When I run the silver stars I have to re-wire the pin connector to get the lo-beams to work, then When I switch over to high beams I lose a low-beam ? VisaVersa When I wire it to the way the xtravisions where I get a little glow in high beams when Just the lows are on.

I must have a bad ground somewhere....

I want to just re-wire the whole headlight circuit from the firewall out. Using the old Low/Hi wires for the relays switched power.

My plan is to run two inline 30amp fuses to two 30amp relays. One for hi, one for low like Im currently running. Do I Need to run two relays for Each light ? Totaling 4 ? 2 high 2 low ?

Im going to run all 12awg wire and solder and shrinkwrap all my connections too. I just recently wired up a electric fan using all 12awg and solder connections. Turned out very nice.


Thanks for any help guys, I want to get my headlights dialed soon. The relays made a big difference already. Now I just want the wiring to the lights to be overkill

this is the way im gonna do mine when i get other bugs worked out.

Two relays is all you need. If you can find them they make realys with dual 87 terminals http://www.suvlights.com/product_inf...roducts_id=119 that way you can feed each light from it's own terminal. I like to wire my relays with the 85 terminal as the ground because some have diode across the 85 and 86 terminals.

Thats good info. I wasnt aware of a dual 87 terminal relays like that.



Im wondering If I should go 85 ground, That could possibly be where im getting power bleeding through ? Would you then run 86 for the switched source ?



Im also having a hard time finding 12awg lead relay plugs, I can find 14awg leads all day.

Im going to mess with it some more tonight and post back....

Swaping the 85 and 86 terminals wont cause the issue you described, I do it because (I'm anal about it) and if you plug in a relay that has a diode across 85 and 86 you'll short straight to ground and fry the relay. I use the relays with diode's because when the field suddenly collapses on the relay you get a voltage spike that can damage sensitive equipment.

The way I do it is:

85 - ground
86 - switched source from the headlight switch
87 - out to headlights
30 - 12v in

Thanks for posting the drawing and info Travo77 and Glock35ipsc I need to do just that on my 71 as I have lights with H-4 bulbs that tend to be hard on dimmer switches.

That may be on today's list of projects.

Thanks for the info guys, Im going to gather up the material and try and tackle this over the weekend.


I will keep this post updated

Ok so I had to drive my truck tonight for about 30 miles in Pitch darkness....Me my truck and my lights....




And I have came to a conclusion, Ole' Blue Needs a H4 Euro code conversion.

I remember Hella making some Non DOT approved lenses that where Euro code ?

I want to go E code Hella lenses with a H4 bulb on the top lights. The high beams would still have to remain sealed beams ?? Or could I convert them over too ?


I realize this could get expensive and lead to HIDS

But I love some good lights, It must be a Surefire thing. ( If you own one you know what I mean )



Nothing beats pure focused light with no shadows... Every time a Benz or BMW passes me on the freeway at night I get jealous



Anyone have any good suggestions for a H4 conversion, and Not the ones in LMC. I don't really care for the look of the Len's.


Thanks

[hessian18]

Any input ?




So far from the searching I have done, Hella 165mm lenses are what I will need, along with a set of H4 PIAA drivers and a set of H7 PIAA drivers.


H4's for the high/low and he H7 for high beams.


All wired up with 12awg wire and 30amp relays..


If I get this started I will keep posted
