Blinker issue new painless wiring

Well guys ran into a little issue. I recently just got done installing a painless wiring harness in my 67 c10. Everything works Except, when i turn my back blinkers (front blinkers working perfect) on with the headlights off they work fine. But when i turn the headlights on only one blinker works. The weird think is when i take out the bulb to the blinker that is working & install it on the one none functioning it works. So i figured it was the bulb took a bulb off a 72 i have here & it works when the headlights are off only. But once again when i put the bulb that originaly works on that side it works perfect. Went to go pick up some new bulbs but didnt noticed they say 2057 & the lightbulb thats working is 1157 but it fits perfect & works but once again only with the headlights off. Do i really need the exact same bulb ? Or could it be a ground issue ? Sorry this could be confusing to read, but explained it the best way i could. Thanks in advance guys !

Re: Blinker issue new painless wiring

Stock is 1157 and 2057 is a tad less bright but runs cooler.
Same base and totally OK no matter which you choose.
Both will work but because my lenses are stock and quite old, I use 2057.

For sure, use the 1157 on a trailer because they are brighter.

Does anyone know anything about 2357 bulbs?

1156 won't lock into a tail light socket because the nubs on a 1156 are directly
across from each other and with the 1157 (taillights) they are offset.
Plus the 1156 has only one filament. The 1156 is used in the front of the truck.

If my memory serves me correct a 1157 2057 2357 are all the basic same double filament bulbs. A 1156 bulb is single filament and is used in the backup lights. Front should also be double filament

Re: Blinker issue new painless wiring

Are they the same brightness? Crossed wires on the one side?

Re: Blinker issue new painless wiring

the 1157 2057 and 2357 all are 8.26 watts on the low side, and the 1157 and 2057 are 26.88 watts on the high side(brake,turn signal). The 2357 is the same watt on the low side, but is28.54 on the high side. hope this helps. I am using 2357 bulbs in both front and rear on my 69 as they show up better on the brake,turn signal side.
