Hi all
I have some 5mm LEDs in my car headlights which automatically come on when the vehicles ignition is turned, for some reason some of the LEDs have blown and now sure why, they are all 12V rated with resisitors fitted as standard.


What I put the ignition to the first click they come one then when I crank the car over they dim for a split second then brighten up when the cars running I wonder if its this thats causing them to blow if the alternator has a voltage spike?

I have the LEDs fitted like this (lights going up)

they have blown about 3 times now and to fit them is a real pain as I have to take the lights apart but I love the look of them.

is there anything you guys would recommend doing or what LED bubs to use, would be greatly apprecitated.
 
Well, if you have fitted them, maybe you need to visit an auto electrician.......

If the manufacturer fitted them, then a trip to the dealer is in order.

thanks for the comment... I know how to fit them as I did them myself, all i want to know is what is the best method to use to stop them from blowing, I am using LEDs with resistors but obvoisly this isnt suitable, is there another type of LED is best to use, or a regulator that could solve the issue of the LEDs keep blowing
