This might be another case of a small, rare problem gets magnified over the 'net.
For me, I have about 3,000 miles on my HID's (cqlights.com), hi and lo. Absolutely zero problems.
Absolutely wonderful upgrade.
I mounted the ballasts and igniters in the mess between the tank and the beak. Could probably get pics, if wanted, but ... pretty comparable to how many others have done it. Big zip ties. Survived lots of fairly punishing off road (it wasn't the terrain so much as how poorly I ride off-road
The only downside I've found? It's made me incredibly lazy about mounting my FF200 fogs on my Terra Nova light bar ... which just sits naked on my GS ... looking, for all the world, like a fixed-wing.
Jump, man, jump.
