Yes, install 6 volt bulbs....unless you have upgraded your bike to 12 volt, in which case, you may have a partially grounded wire or a bad ground connection.
Installing LED bulbs by themselves may not work, (as turn signals)....they may not activate the flasher - you may need a "load device", available online through some of the electronic lighting companies. Signal Dynamics comes to mind - others are out there as well - maybe, even radio shack.....
As stated earlier, I would install regular 6 volt bulbs....but that's just my opinion...Bench Mark Works can probably tell you exactly what you need.
The bulbs I received from Bluemoon are 6Volt, 3 Watt. The wattage is too low to be visible, especially in daylight. I think Hella/replacement bulbs are 18 Watts, (according to Bench Mark catalog). Maybe, order new bulbs from Bench Mark Works?
I finally got my turn signal installed, I am quite disappointed at the brightness of the turn signal. It is useless, no one can see those lights in the day. the light bulb says 12V 5W. I wonder if any one changed to brighter LED bulbs? I saw some 31mm LED bulbs but they are rated at at 8V+.

I see that the Bluemoonscooter eBay post now states that bulbs are 12V.
Are you pleased with the overall quality of the ss bar-end signals? Does the stub fit into the 18mm handlebar hole properly, the cheap chrome one that a friend gave have stubs that are too large, around 20mm diameter?
The unit is solid stainless steel, very heavy, but quality is poor. there are pits that can be polished out. they look like hand made.
For the price, it is a steal. I have yet to find suitable bulbs for it. With the bulb that came with it, it's useless. wiring and installation was a real pain. there was no instruction. I had to remove a few times to get the correct Right /Left.
After looking at the signal setup from Bluemoonscooter, I decided not to install....but, I am reasonably happy with their sidebags, even though the paint job suffered rough handling prior to shipping...
