Turn Signal Lens Issue

I noticed the right rear turn signal lens (the clear plastic cover) has parted ways with my Speedmaster. I've ordered a new one, but I don't see how it had been attached. I tried to remove the right one to see whether it was simple "lefty loosey" turn to remove it, but it won't budge. I don't see any flanges or tabs in the housing of the one that lost its lens that would capture/secure the new lens. How does one remove the clear plastic lens and, more important, how would the new one be secured into the housing? I note there is a cutout on the underside of the housing where I'm tempted to insert a flat blade screwdriver and turn it, but I don't want to break anything. Does the lens just snap in?

 

So, it would appear it either snaps into place or, because it's an LED and therefore supposed to last till the cows come home, it might be glued in and not meant to be removed. Just replace the whole stalk if one of them does take a shit?

I guess I'll find out when the new one arrives.

Thanks for the responses.

 

Great information all! Thanks. I will file an after-action report on the result when I get the new lens.

 

After Action Report:

The new lens came in the mail yesterday. It has cut-outs around its rim that correspond to tabs on the inner rim of the light housing. The cut-outs are two-tiered and look to be made to partially turn on to the tabs on the light housing, then turned further with greater force to lock the lens in place. It looked pretty straightforward as described by RevPaul (thanks, Rev). But, of course, nothing is as easy as it looks. The new lens would not even fit into the light housing. Upon closer inspection I observed that there were broken off bits of the old lens behind the tabs in the light housing preventing the new lens to fit in. I had a bugger of a time working them out with a set of picks, because they were in the "locked in" position behind the tabs, but I got them out after some tedious fenagling. The new lens then fit in place onto the tabs in the light housing. A slight turn clockwise got it hooked on the first tier of the lens cut-out, but it wouldn't snap into the second tier of the cutout. Just the smallest bit of light oil on the cutouts, a slight push on and turn a bit, then a hard push and turn a bit and it locked into position.

Bits of the old lens stuck under tabs:


Here's what I was able to pull out:


All done:



So, in answer to all the previous speculation, the following questions are resolved for future reference:

You do not need to replace the entire stalk.
The lenses are not glued in.
The lenses do not just snap in.
The lenses are installed in by setting their rim in the signal housing, turning slightly clockwise, then turning further with greater force while pushing in. Removal would be the opposite.
One DOES NOT want to insert a flat bladed screwdriver into the cutout on the underside of the housing and turn it to "pop off" the lens.
