I just contacted Hellroaring Technologies about the LED in my switch on my battery isolator. I broke it taking the switch apart to mount it inside my dash, totally my fault not theres. I realized they are in MT in Polsen. I have been VERY happy with my Hellroaring battery isolator set up. Just wanted to point out that they are kind of local to the 406 club. Maybe they would do a small discount for a small group buy if a few club members wanted to go dual battery? Always nice to support local MT company.
