Brake light issues

[4glover]

Hi guys. My 98 lancer has a brake light issue that i have no clue how to fix. When i step on the brakes all the lights work as they should. If the park or drive lights are on, and i step on the brake, the left rear light goes out. I've changed the bulb and this hasnt solved anything. A little advice on the subject would be nice Please and thanks!

check the bulb is fitted propery, if its a dual fillament bulb it has two contacts at the end. if it isant screwed in properly both contacts touch and when you aply the brake all the electricity takes the path of least resistance (ususally the brake light) depending on how it is fitted. this will cause your problem and is very easy to check.

you might have a short. change out the light cluster board for another one (even the test using the other side see if when you swap them over you still get the issue

We lost a brake light on my VR4 once, turned out to be the boot hinge had caught the wires as one stage, rubbed through and was shorting, it was blowing fuses though when it happened.

First step would be to throw a test light on the contacts in the light to see if you are actually getting power when you apply the brakes, then trace it from there.

check ground wiring to the light... the grounding screws always rust.....

thanks for the info guys. But the brake light issue just became very unimportant. My spark plugs are now swimming in oil <_<
