Turn Signal Bulbs

A couple of notes from someone who did spend the money--not just to replace a light-bulb but for bright running lights with a very clean installation.
They're very, very bright. Because from where I sit on the R1250RS I can see the front turn signals, when it gets dark they are distracting and reduce night vision. Weiser suggested putting a strip of black electrical tape on the inside of the lens--I went with yellow tape and can now ride comfortably.

The only think that really took getting used to was the timing. As you might expect, the white light goes out when the turn signals come on. When the turn signals stop, there are a couple of beats before the white light comes on. The delay is so pronounced that the first few times I experienced the sudden appearance of a bright, white light in my peripheral vision I thought I was about to be hit by a car which suddenly appeared to the side.

So they're more expensive than Photon Blasters, which have great lighting but the manufacturing...(one could start a business selling accessory mounting brackets for Photon Blaster accessories), but they make me more visible so I think worth it.
