My girlfriend owns her own business making low voltage DC lights. She and her dad ran it for years and he passed away this summer. She fell and broke her leg, so i have been working all of my spare time to help her get caught up with her orders. Once we get her caught up I was going to have her make me up some dash lights for my M813. I haven't had time to see what volatage the stock lights run at yet, I assume 24 volts. She makes, 12, 24, 36 and 48 volt lights, both LED and special light bulbs. One of the lights she makes is a plastic house flood light that I want to put in the cab that will make it nice at night to find things. Her lights are designed for people who live off the grid and use solar panals so they are very effiicient to run. I'll post something once she gets caught up. She has been on bed rest for the past 6 weeks and hopefully can get back to work at the end of the month.
