I installed the
Rigid Industries Dually LED lights. I chose the black, spot beamed version (#20221) since I thought they might be better aimed away from the eyes of oncoming traffic, and they're supposed to illuminate twice as far into the distance as the flood version. I figured I can always add some diffusion to the housing if I want to soften the light output.
The build quality seems excellent. They feel solid. The case is made from just two aluminum pieces.
The lights ship with a well made wiring harness that Y's out from +/- battery connectors to a pair of water tight quick release plugs. The two fixtures have about 6" of nice jacketed cable, terminating at the quick release plug. Rigid expects the lights to be mounted using the included brackets that attach with 6mm bolts.
I removed the fork reflectors and mounted the fixtures (without the brackets) using long 1/4" bolts since my local hardware store didn't have anything long enough in metric. I had to drill out the 6mm pathway for the bolts in the fixture to fit the slightly larger diameter 1/4" bolts. The store also only had one steel 1/4 x 3/4" spacer left too, so one of my fixtures is temporarily installed with a plastic/nylon spacer. I used star washers on each side of the fixtures to dissuade the lights from slipping. The bolts, which also help hold the plastic front fender, are torqued tight, but not extra tight.
Since the light draw less than 2 amps, I wired them directly into the unused BMW alarm socket in the relay box along with my USB phone charger. The lights will automatically be turned on only when the ignition key is in the Run position.
In full sun the lights are waaaaaaay brighter than the headlight, and they're very directional. I could not stare directly at them for more than a few seconds from 10 meters away. I've aimed them down a bit.
Going for a ride a little later and will report back.
