Brake light Problem

[Razor]

hi

I noticed last night when I was driving another car and following my 240k the brake lights goes off when braking

Headlights on 4 rear round red lights are on but when braking ride hand side brake light goes off but left side brake light works fine.

any ideas?

checked fuse

checked bulbs

all seems to be fine

Did you visually inspect the bulbs, or did you use a DVM to insure that the filaments in the bulb aren't open (broken)?

If the bulb is indeed good, then you could use a continuity tester or the DVM to insure that the wiring is ok. Basically, you want to make sure that there is a measurable voltage on the lead when the brake pedal is depressed. Just guessing, it should be around 13-14 Volts with the car running, probably 11 or 12 volts with the car off, but I'm not sure if the voltage is reduced elsewhere in the circuit.

A wiring diagram for the brake lights would be a big help to make sure you have the correct wire.

I noticed something new.... 2 brake lights work when headlights are off as soon as you put the headlights on if you press the brake pedal the right side brake light goes off (both filaments)

With two of my 240Z's, check your grounds, that was the problem on both my them.
