Haven't seen one around but maybe dimecitycycles.com or ryca might have one that you can work with.

On a note, do you have the original rear turn signals available

Mine are at the sides on my plate and are quite visible.  I think you shouldn't worry about it.  In fact, I like it better than the stock location because both signals are in the onlookers frame of vision from more viewing angles.

Stew:

I looked at those lights you posted.....and although the bulb is oriented in the proper directions - there is no reflector to focus the light out of the housing.  I am guessing the lights aren't going to be very bright.  (You should hook them up to a battery in the daylight, then walk away a couple hundred feet and see if you can see them clearly....just like you want an approaching car to be able to see them).  M experience with plug in LED bulbs....is that they are not as bright as the filament bulbs.

I know I sound like a broken record at times over these inexpensive and small Chinese built (non-DOT approved) lights - but I do want you guys to be as safe as possible and not get crashed into by somebody that could not see your turn signal flashing.

(The sport bike guys are really bad about this....they take off really nice turn signal and brake lights - and put on cheap LED stuff that is barely visible at night....and invisible in daylight).

Ok...got a couple of pics at lunch.  

Here's the lights in "running" mode. Note the new light temporarily taped to the left of the reflector. I captured the pic with the stock left "blinker" on and the right one off for full comparison.

In those photos they appear visible.  Cameras don't operate the same way your eyes do.....and I suspect you had to be pretty close to get those photos.  You need to use your eyes to make a judgement about how effective the lights are going to be in "real world" conditions.....the distracted soccer mom barreling down the road to get her screaming kids to practice!

Take the same photo with the sunlight hitting the lights.....like they would be when you are riding away from the sun in morning or evening conditions.....that is when the lights are really being put to the test.

I have been on a few group rides with folks who had small turns signals, and they were really ineffective...you just couldn't see them when the sun was shining on them.

This will be my last "rant" on your thread......I really want you (and the other riders) to be safe.

You very often use your turn signal long before you ever hit your brakes and turn the brake light on.  The Savage has a good deal of compression braking, and often you can just roll off the throttle before you get to the intersection where you are going to turn.  You also may never use your brakes when changing lanes or pulling out to pass a slower car......and if somebody doesn't know you are pulling out to pass as they can't see your signal.....they may attempt to pass you both at the same instant you decide to change lanes to pass.  In my opinion.....having bright, visible turn signals is very important to your safety.

You might also look on eBay to find take-off turn signals from OEM bikes that are DOT approved.  I am not aware of which bikes use red running/turn signal lights on the back.

I also believe that somebody was able to find clear lenses for the Savage Turn signals.  If so....you could use a pair of front turn signal housings from a Savage that have the running/turn signal bulbs.....and use red 1157 bulbs in the housings.

This is the brightest 1157 LED bulb I can find - but it is a bit ovesize:

This one is the stock size - but is almost half the output:

Stew,

That should work fine.

You might want to consider getting some fender washers (large diameter washers) to reinforce the fender where you drill the hole for the relocated turn signals.
