About two weeks ago I installed an ebay integral tail brake turn signal with a tusk led flasher relay. Today the turn signal indicator bulb quit working. Is this a coincidence? The bike is a 2012 with about 7500 miles on it.

Howard this question must have got lost in the stack. Was it just coincidence? Did you replace them and everything working now?
Off topic what rifle case is on your bike, and how is it strapped down?

Sorry for the late response sp. I think the bulbs burning out was just coincidence. I just installed some cheap led bulbs from amazon that worked in the high beam and neutral indicators, but will not work in the turn signal indicator. The turn signal indicator is working just fine with a regular bulb though. The gun scabbard is the old style Kolpin with the 1/2 inch mounting holes. I welded a !/2 inch nut to the bottom of the cycle rack, which the scabbard is bolted to. the bottom of the scabbard is held back against the passenger peg with a short bungee or tarp strap.

Does any one know why a led won't work in the turn signal indicator?
I don't know. Mine acts just like yours. I have led turn signals and an electronic flasher but had to leave the incandescent bulb in the indicator. For me it wasn't worth figuring out but I'll keep an eye out here if anyone knows.

Are you guys running LEDs in all of your bulbs, except the indicator and headlight? Did you buy a kit that included all the LED bulbs or did you just cross-reference each one?

I replaced my rear tail light and turn signals with an integrated one. installed an led flasher , and replaced the indicator bulbs with leds with the exception of the turn signal indicator. I am still running the stock front turn signals. It seems like I have seen a post that cross referenced all the bulbs on here. I think it may have been posted by Qwerty.

I read somewhere that when there is a single indicator light one needs to install a diode in the indicator light curcuit when switching to LEDs. I believe there is some kind of cross feed issue

I have LED signals, LED indicators with no problems. I do have a solid state flasher as well.

pulled this off the Pro cycle web site from an add for LED signals

! LED turn signals require an LED flasher

! Bikes with single dash indicators require a diode kit

Thanks again troll. Your google-fu is stronger than mine. All I could find is the need for an led flasher or diodes on each turn signal, nothing about dash indicators.

The reason that LEDs won't work with a standard flasher is because of the clever way that flashers work. They depend on a current drain as you would find on an incandescent lamp. What happens is that when you flick on the turn signal switch, it sends a small amount of current through the flasher module, which heats up a pre-stressed bimetalic strip, and then it bends a bit and jumps sideways, like a kids clicker toy. That closes a contact, shorting it out, and stopping the heating and bending. It cools, bends back, and starts the whole heating process all over. LEDs draw so little current that it doesn't heat up the bimetalic strip enough to click over. A solid state flasher is designed to pulse the current, irrespective of how much current is being drawn.

Nice description of an old style flasher CNC200... that is why one hears the click....click as the flasher works.

The led in the neutral indicator is already starting to act up, so when I get the 10 led's used up that I bought I may just go back to regular bulbs.
