Default Why am I blowing tail lights?

2011 FXDWG
I bought it in May 2012 with 9500 miles on it. In the 3 months/3500 miles since, I've replaced the right rear tail light three times.

It's only the turn/brake filament that's burning up. And it does look burnt, not simply broken/shaken loose. I know QC on 1157 bulbs is probably not terribly stringent, but still.

It's not like it's happening right after I ride in the rain, or after I hit a particularly nasty railroad crossing.

All other lights and (as far as I can tell) all other electrics work fine.

A couple of weeks ago I relocated my turn signals and license plate with the Great Bike Gear bracket, and in the process I pulled and checked the wiring and connections on both sides - no breaks, rubs, or kinks in the wires.

So ... something wrong?
Normal for a rumbly Harley to shake stuff loose?

And would an LED run/turn/brake conversion solve this?

I had this problem and the dealer warrantied the bulbs. They said there was an issue with recent bulbs the Harley made.

I'm on the fourth bulb now, and the last 3 have come from Advance Auto Parts.

Should I really buy HD bulbs? I think not.

Usually blowing bulbs when its just one bulb is down to a poor contact, either a loose connector or the bulb socket.

Have you checked the wiring harness under the fender? Maybe the wire for the brake light is frayed and grounding out?

Same thing happened to me. Went through about 8 bulbs, every brand I could get a hold of. Very frustrating!! I switched to the Run-Brake-Turn LED strip last week

I haven't pulled the bulb socket out and checked it yet. I'll hit that tonight.

Nope - I checked the wires end-to-end when I moved the signals and license plate.

I got it from Chromeglow http://www.chromeglow.com/catalog.as...showprevnext=1
I went with 11" and it is a good length for my rear fender.
The run/brake splits in half for the amber turn signal

Did you buy a motorcycle specific bulb? My guess is that you picked up a standard car bulb. The bike ones have more support arms on the filament avoiding breakage.
