    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?

    A picture may help your enquiry?

    Could it have been glued and therefore not intended to be dismantled assuming we are talking LED.

    If it's anything like the Thunderbird Storm then it is just a push in so that cutout is probably as you suspect to prise it off.

    From memory it's a sealed unit. I had to replace one years ago. Don't try to separate it.

    Just guessing but i would have thought they would just be a snap on item. If at all removable.

    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.

    From memory again (not so reliable these days) it's a one piece unit comprising stalk and lens complete.

    Hi @Fork Lock

    Sorry its taken a while to reply, and I'm not sure if this helps.

    I'm attaching Triumph's instructions for their accessory LED elements for the indicators on Bonnevilles. I downloaded this because I'd bought their clear lens conversion for my Street Cup.

    Based on nothing but observation I suspect Triumph use the same components for most if not all their Bonneville based indicators: Unfortunately your picture is too small to get a good close up of the way the lens might fit)

    LED Indicators A9838032-EN.pdf

    On my Street Cup the lenses use a twist fit to fit the lens. They were very difficult to twist (it felt like they were glued in) and I had to hold the indicator stem against the force I was using to avoid either bending the mounting bracket or tearing off the whole assembly.:cold_sweat:

    It was the same when fitting the new lenses, initially by hand: They never felt as secure as the ones I took off, so I went round them with a strap-wrench (again counter holding the indicator stem) and they each twisted a little more and clicked into place.

    So when you get your replacement lens, proceed with caution.

    Hope you get it sorted:cool:.

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