Headlights super bright only when I pull lever

Do all vehicles do this? Is it running on both beams then, only? If so, why don't they have it do that then? I can actually see when that happens! I'd just LOVE to be able to see like that.

Try YOURS once and see what yours does.

 

Not all vehicles do that. You can wire up a relay so all 4 are on while the brights are on. They actually make wiring/relay kits for certain vehicles.

 

Who would be the most knowledgeable on this for a particular car? And is this something many people have done? Or is it more commonly done than people would think?

 

I've seen a handfull of Chevy trucks with it done. What vehicle do you have?

 

It runs on low or high beams but not all four at a time, pulling lever is meant only to ask oncoming trucks or cars to switch to low beam when driving at night

 

Yup, flash to pass is what they call it. Most of the newer vehicles have this, but some still do not. But, at any rate, any vehicle can be wired to have both low and high beams on at the same time, while in high beam mode.

 

With both going sustained and not for the split second that I refer to when I pull on the lever to go from low to high beam - will that be a problem with additional current flow with the way the headlights are fused?

I highly recomend everyone some night try YOUR vehicle to see if yours gets brighter in this way.

 

My '90 jeep cherokee also does that. Kind of handy when you need the extra light but I'd also worry about the extra current flow if it was kept in that position.

 

Kits are out there, maybe not for your application though. But with a relay and some schematics, you could do it. Here is a link to the one for GM trucks,

Thanks. I am going to look into this. I'm going to ask around. This is most interesting.

I just stumbled on this by accident, or rather happened to notice this one day recently, after all these years of driving, as to how the lights would get noticeably brighter just in that short while I click-held the light lever momentarily. What a huge difference in what you can see down the road.

 

My 04 F-150 does the same thing, as did the 99 I had before. It's probably only vehicles with two headlight system where both headlights have two filaments, one for low beam, and one for high. We also have a Honda Odyssey with four lights, the outer two for low beam, then all four for high. It really lights up the road. One little idiosyncracy on my 99 F-150 that I discovered by accident was that if you pressed the cruise control ON button at the same time as the speed set button, the horn honked. The dealer could never explain that to me, but another used 98 that he had did the same thing. I was disappointed when my 04 didn't do it.
