No, I just make my own from a strip of aluminium alloy bar 2.5" x 1/4" thick. The brackets are from 16SWG steel so very cheap to make and easy to fit.
The 'works'-type lamp bars look very nice, but I designed mine so that in the event of going off the road on a rally the brackets would bend and not damage the front panel. I once hit a 50 bar gate on a rally and the idea worked - I just broke the lights and bent the lamp bar brackets.
