By golly, this worked, the 660 weighed more, I checked the 660 bulb and it had fluid in it. The 800 didn't have any fluid in its bulb. Do I need to get one of these thingamajigger's? Anyone recommend where I drill a pilot hole into the bulb to place fluid in it? I don't really wanna go to Driven in Casper and spend money on Polaris Factory fluid taillight bulb, unless I am unaware of a recall on the bulb that was in the 800.
You need a race bulb.
Get it from a local racing team.
