Greetings!

I just figured out that if I position the headlight stick a certain way in between low-beam and high-beam, both low-beam and high-beam lights remain on, instead of just the low filament or just high filament.

Question: Can this cause a fuse to blow or harness to melt? I would like both to remain on for about 20 minutes MAX while driving in the countryside.

Thanks!

 

It's not a good idea to keep both low and high on at the same time. You'll have 2 filiments burning which will heat up the bulb so much it could cause it to explode in your headlight housing. Thats not going to be fun to clean up. My advise to you is don't do this. Especially if your running 80/100 bulbs.

 

To add on, you've also got only one ground circuit. The circuit can withstand temporary overwattage conditions (e.g., switching from hi to lo and vice versa) but if you run both at the same time for extended periods of time, you'll be running too much current through the one ground wire that you'll probably burn the wire.

It's not fun fixing damaged wires, nor is it fun if you had an electrical fire. Don't do it.
