I used the accel one off of eBay last month. The exhaust had to be removed in order for me to get the original off. I used a 1 inch open ended wrench. You have to use the hex side.

Hey just about to attempt to replace my rear brake switch today, do I need to bleed the rear brake? I was told that if I apply a tiny bit a pressure to the lever and hold after I remove the old switch and while installing the new one I can avoid bleeding. I know I should take it to the dealer, but $120 seems crazy to me.

Yes, you will end up getting air in the line, flush it through, $120 is well worth it if you are not comfortable doing this work :deal:

I agree with $120 being alot to bleed brakes. Bleeding brakes is not difficult. However, if you have ABS you can't do it in one shot without the dealer's service tool.

You could bleed it normal and go for a couple of short rides and trigger the ABS to get the old fluid and any air pushed out of the ABS passages into the main line.
[Edit]
... I know, not the safest way but it works dangit.

I own a 2009 VRSCAW Nov 2011 the brake light switch went bad. Replaced it with the 72023-51D from Harley. Now its Nov 2012 and I am replacing it with a 72023-51E from Harley. Let's see how long this lasts. I'm in Hawaii and I needed it fast but I will definitely look aftermarket for the next. I have gotten better at taken off the exhaust though.
09 VRSCF with 44K just replaced the switch with the 72023-51E part. BTW this is the first mechanical failure for the bike.

The RB401 from autozone is not compatible. Way too big/wide for the plug.

What year? It looks like the ones from J&P are only compatible 2007-2017. I've got a 2003 VRSC and mine just went out. The photos look like it will fit, but not sure.

My switch failed and had small pieces of rubber stuck in it from a failing (internal) rear brake hose - ( it also gets baked from exhaust heat ) and the rear brake caliper must be properly supported during tire changes when the wheel is removed ( don't let it hang by the hose ) or that will also damage the hose and put pieces of rubber into the switch, and even leak externally. These hoses are getting hard to get from H-D but are available elsewhere, some much better than OEM for heat resistance. Need a switch ? Hose older than 8-10 years ? Replace it.
