hey people ive tried 4 pairs of head lights and all turn out week and there all bran new but once i try them on a different there all bright and strong....
what would it be from

 

i dont understand. You mean the bulbs? What gen is this for? My light output seems to be "weak" also, doesnt shine the road up too good. I have stock headlights with Silverstar bulbs.

 

i have a 2nd gen 87 lude, and only my left side is week , its dimmed out like the light is going bad, got a new one and still dimm. any one know?

 

yea friken bulbs... its so **** i cant see whats infront of me... and my dash is weak when my lights are turned on. thats the only thing i hate in my car is my tupid electrical.
no one knows what it is. lights are weak lights cause my temp gadge to say its over heating, dash board goes weak barly c the temop and petrol gadge in the day if i got my lights on.

 

check out ur grounding points on the car. battery by the head lights theres 2 of em one on each side and then check the motor to the chassis

 

ok the battery has one ground from the negative to the chassy and thats it. where would the motor to the chassy be lockated. sorry newbie at this grounding stuff...
and what would i belooking for low contact or just not connected..

 

sorry to not be clearer
the headlights have there own ground to the body.
the battery has one
the motor should have one around the battery or starter on the tranny or motorj just follow the neg cable from the battery

look for corrosion or missing pieces or rust.

 

check the fuses
