I recently installed some LED visibility lights in Amber from Skene Design. You can also get them in white.

They're pretty cool. I was originally going to re-use some 55w amber fog lights I took off my BMW before sale, but the 55w draw was bugging me given our limited juice, and then I discovered some cracks in the mounting flanges, and decided to nix them. I mostly wanted a daytime running light (DRL) for daytime visibility, not so much for night time road lighting.
I did some online review and searching for LED visibility lighting and these seemed the most developed.
They only draw 3.5 watts!
Not only do they emit a very noticeable amber glow that makes the front of the bike seem more noticeable to oncoming traffic, they also pulsate to create a slight strobe effect. This can be turned off and I'm still debating it, I don't like being obnoxious and am not a fan of modulation.
But when you do need to be a bit obnoxious, there is an alert feature where you tap your brakes two times within one second and the lights pulse a four flash and then slower four flash pattern to really get someone's attention, like approaching an intersection, or any turning, oncoming traffic.
You can also get them to run with your front turn signals as well.
Excuse these poor garage photos, but you get the idea. They were pretty easy to install, the wiring was the most challenging part. I mounted them on the forks where the side reflectors are mounted. Those are a 5mm hole BTW. It seems like a sturdy non-obtrusive location for them. I wired the power off the factory heated grip connector and ran a wire back to the brake light to enable the Alert feature.
Overall I'm pleased and they seem to be a great solution for what I'm looking for, to be seen and noticed at a minimum of voltage cost!
