- Shoot the transformer output 12 v 20 to 50 w lamp is LED12V 4 w can use excuse me?
- Ok, now are LED lamp to replace the original quartz bulb,Can be used, but there must have a circuit inductance/curtains on tube/semiconductor current limiting device (using single-chip microcomputer control)!!!!!
- LED two head lamp lines do not short circuit is not grounded on the total trip what reason?
- Is a turn on the light when the old jump total brake, if the loop is none on total brake can again.LED lights the short circuit of the internal parts
