    Switching on Lights draining power? And now front side light comes on when braking!

    This just started yesterday. When i am driving in any gear cruising along and i switch on my lights, the car loses power as if if is dying out doesn't matter if i try reving just now reponse whatsoever, only comes back to normal when i change down a gear. Any ideas what this problem could be?

    After Googling and checking the brake light bulb that i replace i found it's only got one connector at the bottom when it should have 2 hopefully i'll replace it and it will fix the side light issue Do you guys think this maybe would be related to the other issue?

    if you put a single filiment bulb in a twin filiment bulbhlder (yes it can be done! lol) when you brake, it can cause the side lights to come on, vice versa as it can power the opposite circuit, i would try that and see what happens mate!

    Got a new bulb (twin filament lol) and things are fine now, it also fixed the power drain when i switched the headlights on, who would have thought 1 wee bulb could cause so many problems thanks guys
