i am working on fixing a brake light on my parents 1995 suburban. The regular lights that come on when the headlights are on come on but the brake light and turn signal (run off the same bulb) wont light up any brighter when applied. I already tried to fix it by relacing the bulb but had no luck.

Anyone got advice? Is the wiring screwed up somehow? :?

start by checking fuses, then use an ohmmeter to check for a short at the light, then use an ohm meter check for contiuity(or however its spelled)

Make sure you have the correct dual filament bulb, and that it'* in the right way. Try it 180 from where it is now.

There should be a slight indexing pin to it, use a volt meter or lamp to confirm the wiring.

btw do the hazards work?

Hazards don't work for the lamp that is out.

Thanks for the sugestions. will work on it tonight!
