Welcome to the Werkz.

Do you brake lights actually work at all?
If they are not working (but bulb is good) you may have ground issues.

9j wheels... Try 255's max.... I have those on my 7... But a 5 is pretty much the same !!!

As Brett says too !!

before you buy ANYthing, check how the bulbs are seated, you lock in the tabs and the twist to make contact with the circuit. When these bulbs carriages get older and oxidize, the connection can become loose and unreliable. If your bulbs are good, and seated properly in the carriage, turn car on, put a brick on the brake pedal and then fiddle with the rotation on the bulb carriage, if you can get it to work, you'll need to replace those, but that should get you a factory fit and the car won't bounce the brake lights out of contact.

Went through this with my '92 525i. This kind of pseudo-short will also play havoc with the brake-light switch warnings.

Hope this helps.
