Headlight grounding help

Question

my company dump truck keeps blowing headlights up and i think its a ground could i ground the headlight to the frame or is that not a sufficient ground

Answer 1

make sure the bolt isnt rusty and there isnt paint where its grounded

Answer 2

Three things will make a headlight quit working.

High Shock

High Vibration

High Voltage

I would suggest that if the voltage to the headlight is correct and there is nothing you can do about the vibration and the shock is to use a Heavy Duty H4 Bulb.

A H4 headlight has a replaceable bulb, these can be found at Pep Boys and Kregan Autoparts as well as online store. I’m guessing you have 7” round headlights. I would use Harley Davidson Bulbs in these headlight lenses. The Harley Bulbs are made for rough service with all the low frequency vibration they have at idle.

Answer 3

If the problem your having is blowing headlights, it sounds like you could have a short to ground. In other words the one of the positive wires is contacting ground. Grounding the negative to the frame most likely will not help you, i would check the positive connections first and work from there.
