LED replacement bulbs

You have to look at the LED lamp and figure out where the diode’s are facing. Incandescent lamps radiate light almost equally in all directions. The shape of the reflector or housing and the grooves on the lens direct the light in the direction you want. LED diodes really only project light out the end. Some "replacements" have the correct base, but the LEDs all face straight out the end, or 90° from the base, or some that have small diodes on a cylindrical "drum" facing in all directions, (would SEEM to be the most appropriate). Not saying don’t change to LED, just be careful to make sure you get the "finished" light output you are seeking.
While bright tail lights are nice, consider that it might be just as bright as your brake lights, so
1. People will think you are driving around with your brakes on which,
2. While, Yes you will still have the actual brake light, but there is not as big of a change between just tail light and brake application.
you want to catch peoples attention to cause them to react.
Thanks 72Duster440, I had been looking at the Phillips extreme vision, but I couldn’t remember the name. Those looked like they would work well.
