I got a reply back from tech support regarding the indicator lamp not working. . .
" I don't know for sure if current draw is the problem, but odds are that is the problem. Measuring the resistance of the incandescent lamp won't be that useful for what he is trying to do. The resistance of the incandescent lamp will change quite a bit when operating, so it won't help to know the resistance when the lamp is off. Measuring the LED lamp resistance will not tell you anything because it is an active device.
If he can measure current, that is a more meaningful measurement. I expect the incandescent to draw something like 4 or 5 amps. The LED headlamp draws only about 2.5 Amps in high beam mode. (and varies a bit over temperature) To make the LED draw the same current as the incandescent will take a VERY powerful resistor. (24 Watts to 36 Watts, best to target a 50 W capable resistor because it will be in the hot engine compartment) These resistors will get very hot and will need to be properly mounted and mesh shielded to prevent them from melting stuff that falls on them in the engine compartment. (or burning you while you are working on something else with the high beam lamps on)
I don't believe it would be necessary to match the current of the incandescent lamp. It may only take another 0.5 Amp to get it working. That would be something like a 10 Watt resistor of 27 Ohms. Still will be hot, but not as bad as the 50 Watt resistors. Still needs to be mounted and mesh shielded to prevent them from melting stuff or burning you. Get a 1/2 dozen of them so you can add them in until the indicator starts working. (each resistor added in parallel to the lamp will add about 0.5 Amps of current) 6W incandescent bulbs can be used the same way, but it will be a little weird having lights inside the engine compartment. An adjustable 50W resistor can also be used, but I don't know how one of those resistors will like living in the engine compartment. (corrosion of the exposed wires in the power variable resistor is my concern)
Do not try this if you don't know what you are doing, it is possible to make some very bad mistakes with resistors of this power range.
It is easier to just add a blue 12V indicator lamp that is wired in parallel with one of the lamp's high beam wires and use that as the high beam indicator. (but doesn't look so good)
I hope that helps you. There is not an easy way to make an LED headlamp act like an incandescent."
Based off what I read in that reply I could use resistors but as I was worried about from the start, heat is going to be an issue with using them. . Using the small incandescent bulbs in-line with the low beam wires seems like an easy fix, I may try this.
