Technical Low beams on with High beams

Low beams on with High beams... Has anyone wired a single bulb dual element so as to have the low beams stay on when switched to high beams? Single headlight pots. Lamp is a peanut bulb halogen dual element.... would the heat destroy the lamp in quick order???
Thanks, for anyone that has tried this.. Regards

 

Are you talking about the old style sealed beams? They can do that safely......
but there's no such thing as a free lunch. There will be more heat and the added heat stress causes shorter bulb life. If you rarely drive at night, that may not be a a big deal.

I'm not an expert so "duck and cover" as needed.

 

If your high beams don't seem to be enough, are your head lights aligned properly? If you are rally driving or are out in Baja you might have to add driving lights so you can see beyond the speed / braking capability of your car's high beams, but otherwise why would you want to do this? Heat would be a problem IVO the extra watts, but ******* off on coming drivers might be your biggest worry. Gary

 

If the light could take it (which I doubt) the switch will cut out from the heat. If the switch doesn't have heat protection it'll burn out and maybe even ignite from the outg***es of plastic parts or the wire. Add driving lights on their own circuit.

 

Use relays to turn the low beams back on when you switch the high beams on, the factory low beam circuit stays intact and there is no worry about overloading the switch. And yes the bulbs should take it, I've done lots that way

Running both high and low beams at once will sharply reduce lamp life and the extra heat generated may melt your wiring at the lamp.... not a good idea. How much ventilation you have at the connection will affect this. I've seen this tried on motorcycles, and it nearly always resulted in melted wiring in the bucket.

 

They are both supposed to be on at the same time.

 

use a relay to take the extra draw off the switch . on some cars just putting a relay thats switched controlled and have the bulbs wired to the battery made them way brighter on low beam . and also works on high beams also .

 

Says it right in the wiring diagrams for both my headlights and fuse panel.
