The TLR stock headlight has 2 bulbs -each with a high and a low. The stock switch allows only the low OR high to be on -never both. The system can easily handle both the high and the low being on at the same time so why not mod it? In my case I need to mod the stock switch to get the ideal performance out of my triumph headlight. This is a simple mod where you take apart the HI/ LOW beam switch and short the Yellow/ White connection with the white connection. This allows the low beam to be always on while you switch the HI beam off and on

First look	Remove the switch	Making the piece to short the two connections	Y/W and W shorted	Modded
Done	All-on	Low beam
