hey i just figured it out my lef tail light is lighting so much brighter i checked it out and on my left side both lines are lightin in the bulb but on the right side its only one is lightning, i tried to get new ones and they did the same think too wasup with that?
Your taillight is out and the car is defaulting to using the brake lamp bulb as a tail light. Check all your rear bulbs, I'd put money down that you have at least one tail light is out. Make sure you use good Osram bulbs with the silver/nickel base when you replace bulbs.
i changed it like 4 times but its still doing the same thing i dont understand whats wrong with it on the left side both of the wires are lightin but on the right side only the one of the wire in the bulb is lightin i ll try to find another brand i guess thanks for the reply thoug
If this is just for the tail lights there should only be one element in the bulb lighting up when the tail lights are on. If both are lighting up you have a problem. It should only be a single element bulb in the tail lights too.
ean the ones im replacing with they all have dual elements. i ll try to look online if i can find on the internet with one element
It will say on the bulb carrier for the tail light if it is soposed to have a dual or single element bulb in it. For a tail light it should only say 10W in the plastic by the bulb, usually the brake will say 21W. If a socket takes a dual element it would say something like 21/5w meaning that it needs a dual element bulb, one element is 21W and the other is 5W.
