I've been toying with an idea of replacing stock turn signal light bulbs with LED equivalents on my '14 BE for a while now, especially after picking up a set of '15 LED headlights - which, surprisingly, *still* come with regular light bulbs for turn signals.
So I had picked up a pair of 10pc 5W CREE LED bulbs here http://www.jdmastar....rv-motorcycles/. Even though the bulb body is aluminum, it runs its LED chips only at 1W (10W total) to keep them from melting, I guess. To my surprise, these bulbs did not make turn signals hyper-flash when plugged into rear sockets - I figured they put enough load on the circuit to make the flasher think it was driving real incandescent bulbs. They turned out to be a poor fit for GTR rear turn signals though, because their 2-3/8" length makes them get completely covered by and rub against dome reflector caps, so I ended up keeping the stock bulbs in the rear, for now.
Today, while I had the front wheels off the car for spacer installation, I decided to pull the fender liners off and pop these bulbs into the front turn signals. They fit well there, and are pretty bright, even in daylight - but the blinkers now hyper-flash!
WTF?! Why would the car detect these bulbs differently when plugged up front vs. in the back?
