Default No taillights when headlights are on.

Last electrical issue and a pretty big one as the car is black and only drives at night. My brake lights work, my turn signals work and my hazards work. but not a single one of my tail lights work. i don't have a 3rd brake light but that shouldn't matter as it's just unplugged/removed.

1157 are dual filament bulbs. If you look a the bulb socket, it will have 3 wires, one for ground, one for brake and the other for parking. On Hondas, parking light circuit is usually the red with black stripe.

1157LL....the "LL" stands for Long life. Other than the claim they last longer the typical 1157 is subjective. LOL

yes, they'll come on when the lights are off and when they're on but zero tail lights.

no specific one for tail lights



Edit: from what i can see the tail lights are connected to the fuse for the cluster lights when the lights are turned on. i'll try the bulbs, and inspect the socket too as i've seen them corroded.

Make sure the bulbs went in properly, thats the only thing I can think of. Did you check for voltage at the plug?

Cleaned up the wiring regarding the side markers for the JDM Front and it works perfect now.

I used the 3 wire blinker and had just connected the wires not paying attention to color, despite it "working"(blinking) it would not blink if the headlights were on and had not allowed the tails to work. Either way i took out the side marker blinkers.

That's what happens when you use 2 power circuits in a DC application.
