Turn Sigs.

i just received these and making an alum. mount since my mirrors go on the ends of the handle bars.
Very Bright indeed

Chaz, push buttons on the end tips.

they have less expensive ones and they look it.
these are quite heavy for their size.

each light has two lights (each side, one facing forward, and too the rear) i learned a trick from an auto body shop, an old Mercedes Benz would come into his shop they would and paint the inside of the rear amber turn signal housing candy apple red
because over here (USA) tail sigs. are suppose be red.
i have done a lot of electrical in my time and lit up many projects,
but these seemed kinda nice, so i may paint the rear parts where they shine back only.
Amazon also has rear tail lights that have blinkers and wireless remote but the (honest) reviews are not promising.

one more thing each light comes with (2) button batteries #2032 and also sold separately rechargeable ones. i like this place and bought quite a few items in the past from here http://www.batteryjunction.com/
