I'm wondering if anyone has used these projectors and can tell me exactly what voltage drives the high beam sonenoid coils. Is it a true 12vdc or something other than that from the ecu.
While I'm here, anyone know how to easily dissasemble the jdm ebay type one piece plastic headlight units.

 

12 vdc just like every bixenon solenoid. It will probably work off a 9v battery to test. ECU has nothing to do with the coils.

 

If you're referring to halo type that are sealed with 4 clips and sealant.I baked mine in oven very briefly at around 250,came apart very easily.Worked for me to replace LED's in halos.Watch out how the sealant drips onto covers though (messy),and don't "overcook" them...
