Hey all;

Is there any sort of limiter in the relay for head lights or anything?

I recently (For off road use) put in 80/100 watt bulbs and they look no different than my stock 55/65 bulbs.

SO trying to figure out if they should pull what they are designed to pull or if you need to change out a relay to make them work at full power.

 

There is no limiter. The bulb will draw what it is designed to.

The only real "limit" is the gauge of the wire and the fuse.

 

lol..

Well then these bulbs just suck and dont produce what they claim.. they were barley as bright as the Wagner Night vision? (same as silver star's)>>These were the off road optilux or what ever sold by 4wheel parts 100/80's made in korea. (same as the wagners)

if they really are 80/100 i dont see a difference in light output that's for sure.

 

Check the voltage and current draw.

If your voltage is low they won't be as bright as they could be - think poor connections or bad ground.

 

Also, think of the voltage drop from the factory wiring.

Even using the factory (well, in my case ZXe bulbs) and a good relay harness, the lights are brighter.

I didn't measure on my Dakota, but when I did my 1991 Cougar, I picked up over a volt (!!) at the headlights due to the lowered resistance of the wiring (heavier gauge wires, shorter, means less resistance.) And if I had used the higher powered lights, the drop would have been more (more current, same resistance, more voltage drop.)
