s13 Hb Tailights dont work HELP

[werdna]

Just got a 1990 s13 hb and my taillights dont work when the lights car on. They DO work when i press the brake but dont stay on like they should. Checked the fuses and there fine. Any ideas??

could be seperate fuses. ive never checked, but did you check EVERY fuse down there?

unplug the tail light connectors and check the pins. also unhook the battery and clean the terminals. you can also unbolt your engine block and chassis grounds and clean them up.

bad grounds can cause some strange lighting issues.

You do realize it's a dual filament bulb, right? The parking light filament is 8 watts, the brake is 27 watts. They work independently of each other, so the smaller one can be burned out. Check the bulbs.

If good, the red/blue wire going to the tail section has been damaged.

ya the battery is nasty and the battery light is on (so are the e-brake light ,seatbelt light and windshield fluid so i dont no how accurate they really are). Ill have to check the grounds and the wires tomorow. Neither taillights come on so unless both bulbs are out its probably not that. Thanks for the thelp
