But things have changed a lot since I installed my first set of auxiliary lights almost  years ago. Back then, the PIAA s with  watt H bulbs were the hot set-up, provided your motorcycle had suf- ficient alternator output.To install them on my BMW RRT, I had to find an inde- pendent manufacturer of mounting brack- ets and do some custom wiring to activate them with the OEM high beam switch. With about  lumens of output per light and a relatively narrow beam, two s provided a significant improvement over the stock high beam ( lumens). How- ever,since there was no way to dim the s, I could never leave them on for improved conspicuity when there was oncoming traf- fic whether it was day or night. While PIAA is still selling the s (now equipped with  watt bulbs that are claimed to be brighter than the old  watt bulbs), some of the auxiliary light- ing systems available today have substan- tially higher light output in combination with lower power consumption and other improvements. In the Summer  edi- tion of Iron Butt Magazine, Roger Patti- son reviewed the  lumen Krista light emitting diode (LED) lights produced by Clearwater Lights of Rancho Cor- dova, California and concluded: “…Krista LEDs should be at the top of every long- distance rider’s auxiliary light list.” In the Spring  edition,Chris Sakala reviewed Clearwater’s  lumen “Erica” lights and concluded “The Ericas put my prior HID lights to shame in the same way the HID lights had shamed the halogen lights before them.” Advances in Driving Light Technology: The Clearwater Lights Krista 2 with CANopener By Tom Austin Lights dimmed for daylight operation.
