hey there. last year i had purchased the tri bar LED brake light for my softail standard. A few weekes ago a buddy of mine got behind me me and said when i throttled up it got brighter when i got off the throttle it would dim dow. since then it does not work at all. i thought maybe the ground but the shop just called me and said i need a new one. has anyone else had any trouble with this. any help would be greatly appreciated. thanks.
