    Electrical question on headlights all on

    i have LED lamps and want my Low beams to be on with my hi beams. Now the way I see it is to install a large diode between the low and hi beam wires at each light so the current will only travel through the diode jumper when the hi beam is on adding power to the low beam. Sounds right?? I have done the amp loads on the lamps (low beams only draw 3 amps) so a 10 amp/100v diode should be fine. I seen the adapters listed by Denali for 30.00 ea.  just wanted to run it by all of you in case there was another way i missed.

    Them cool blue LED headlights (low or high) are hard enough on the eyes of oncoming traffic. Just saying, it might not be the best idea. People do forget to turn the highs beams down at times.

    Couldn’t you add a wire at the dimmer switch to power both when on high?

    Don’t know if you’re using relays for lights, if so could place diode from hi beam relay to pick up low beam relay.

    My only concern is the heat generated in the lamp (bulb).
    Might cause a failure.
    Do these have cooling fan or just heat sink?
    Just something to consider.

    Good point about the generated heat, might void the warranty or worse, melt down. n

    Electrically it will work. As for heat, 3 Amps 13 Volts = 39 Watts. Some of that power is converted to light some is converted to heat. I find on house light LED's, most of the heat generated is on the base not in the bulb. As for why you want to do it, don't think there is a guy on this site that didn't get an idea in his head and say why not. Don't think you'd be on here if you didn't.

    If this forum can't fix it, it isn't broke.

    Re: Electrical question on headlights all on

    No relays,and dont see the need with low amp LEDs, I only plan on using this feature when I can use my Hi beams. That's not a lot with the traffic on most roads now days, but when you do get to it would be nice. The lamps do have fans and are mostly aluminum constructed. I found another site that makes them as plug in play for my H4 system and they say they use them on LED conversions, so I will try them out.

    May not be a problem if unit has built in fan and the most important aluminum heat sink.

    What type LED lights? Pictures?

    Re: Electrical question on headlights all on

    Hey there just a quick update the lights I ended up with are the Marautos because they are only 1-1/4 deep at the fan. I will send pics as soon as I get the intake back on so I can drive. These probably aren't the brightest lights on the block but are definitely white on the road like a new car. At some point I mite ad the stock fog lights now that they to can be LED, will see.
