Just this weekend, I had removed the fuel tank from the '81 R65 to do the drain, flush n' dry service. Really pleased to see the OEM tank liner in fine fettle.
A very small amount of water in the non-petcock, right side of the tank and a little bit of debris was drained out. Didn't take long for the remaining moisture to be evaporated from the black fuel tank as it sat on the deck in 103 degree Texas heat.
So what's this to do with LED turn signals?
With the tank off, I was reminded of the replacement turn signal flasher I installed after having placed small, streamlined LED lamps on the sport fairing. Rear signals are conventional-bulbed OEMs but on much shortened stalks. Rather than mess with fitting in-line resistors for the front LEDs, I stopped by my FLAPS and purchased a turn signal flasher relay that is used on so many of today's automobiles due to the manufacturer's love affair with LED turn sigs on all four corners.
Plug n' play. Simple deal.
