Can LED lights cause car not to start?
GM has determined that LED bulbs may be the cause of a dead battery, inoperative Start/Stop system, and an instrument cluster with backlighting problems. Many vehicles have a “light out” feature where the modules measure resistance or voltage drop to turn signals, parking and brake lights.
Why is my light bulb not working?
First check the bulb. Tighten the bulb if it is loose, then try the switch again. If a problem remains, be sure the switch is off, remove the bulb and substitute a new one. If the light does not work with a new bulb, check whether the circuit breaker or fuse governing the fixture has tripped or blown.
Are LED lights good for driving?
They can blind oncoming motorists and their brightness also creates a shadow effect which makes it hard to see other objects when driving. With LEDs, you do not have to worry about too much brightness causing temporary blindness to other motorists. They offer a decent illumination that is far better than the halogens.
Do you need to change the headlight bulb?
If your actual headlight glass needs to be replaced along with the bulb, that’s an easy fix, too, as is replacing a bad tail light or turn signal .

It’s also a lot cheaper than asking a mechanic to do it for you.
