I know this is an old thread, but I have used this thread for ideas on how to get an IR light for my truck. I do not have an old military truck, though I think I would like to. I want to put an IR light on my pickup to enhance night driving as it is recorded by my dash cam.
I have an IR light like the ones islandguydon posted above.
I replaced the GE 4811 28V 50/110W bulb with a GE 4454 12V 60/60W.
In order to test this new bulb, I hooked it straight up to a car battery. In the video posted below, you can first see the beam as the power is applied to the left connector. As the video progresses, I move the power over the the right connector. The beam seams to have an oblong affect but seems to be a bit brighter when connected to the left terminal. I was expecting the affect to be a light pattern that was...more round? Or at least larger. Now that I think about it, headlights do have more of an oblong pattern...
How would I go about wiring this? Is power applied to both terminals at once? Or both if in high-beam?
