I believe you will find it is a Sylvania 7507 bulb. The pin configuration is kind of different than most bulb.

Thanks, my friend. I appreciate it very much. I'll let you know after I run down the bulb if it's the right one.

aka BAU15S bulb

I remember that now as I tracked down that number once before. My memory and mind fail me with 70 just around the corner.

I bought some replacement bulbs for my bike a while back and they were hanging out in the garage on my pegboard so I was able to access the 7507 number in short order. I was looking for a brighter bulb, but I never found a substitute that would simply drop in and work.
 
From this thread - Headlamps???





Note that it is very easy to mod a BA15S bulb (which has the bayonet pins at 180 deg) to fit in a BAU15S socket by a quick dress with a file to remove just ONE of those pins.
Even with one pin it will still hold securely in place both physically and electrically.

Turns out its not the right bulb - too large for the housing. Still need to find the right one. Can anyone help????

I don't mean to question your effort at putting it in, but if you check this website and the specifications for the 7507....it is a BAU15s base and should fit your bike. Don't forget, it has those screwy offset pins. I don't know what else to tell you. I'll do a little more looking.

I'll give it a look. I don't know why the 7507 doesn't fit @ksquared socket because it is suppose to be a BAU15s base according to the post I just made to him. Hmmm....
 
It's possible you got one with a larger globe but the base should be correct

BAU15S / 7507 / PY21W all have the same base
 
Not sure if the 16 R3R is different, but i put 1156 (BA15S) bulbs in my turn signals. No Issues with the posts being out of alignment.


Disregard, BikeBandit shows different part numbers for the bulbs between the 08 R3T and the 16 R3R
