Mike Lasher from Side X Side Magazine ran some of the DFR LED Light Bars in the BITD Vegas to Reno Race. This is what he had to say after the race. "We only had to use them for about a 45min on day two coming into the finish line. They were awesome! We ran the 40 on top and 20 on the bottom and never had light issues. I did some testing before we left and I could run the lights for 2 hours and 45 minutes on just the battery alone." Racing helps us progress at the rate that we do and I'm glad to hear such a good review from a very trusted name in the sport.
