Hey Folks,
So I wanted to upgrade the headlights on my HZJ73 Land Cruiser. When I got it from Japan the previous owner had installed Zenon bulbs and after a few months of ownership the aftermarket ballast went. Instead of replacing the ballast, I simply deleted it and got some LED bulbs. These worked fine for a few years, but didn't have much of a seal to speak of, certainly not any kind of IP6X rating. Recently they got wet while I was in the woods and one of the LED bulbs kicked the bucket. So I thought I would upgrade again to the now readily available IP rated 7'' Round LED headlight assemblies.
When I hooked it up, the bulb comes on when the low beams are on, but when switched too high, it goes dim (not out, but certainly not bright enough to drive at night). It has a 3 pin H13 connector, upon checking the voltage, when the low beams are on I am getting 24volts across the negative and one of the positive pins, which seems correct. But when the high beams are on, I am getting 24 volts on both the positive pins.
So my question is, were the original headlights designed to have separate low beams and high beams? Or, are when switched too high beams, are the low beam and high beam bulbs both meant to be on? If it is the latter, the new LED headlight assembly must not be designed for this, as I tested it directly from the batteries with 24 volts to the high and low beam pins. It operated fine.
If the trucks are designed to only have the high beam bulbs on when set to high beams, and low beam bulbs when set to low beams, then I have some other problem (faulty switch?). Any information would be greatly appreciated!
