Indicator Lens…? Am I Being Thick???

Hi Matt what model and year is your machine as the indicators do vary

 

Photos would help.

 

I really dont know but it should be designed to come off if its not LED, how else could you change the bulb? It might be in the manual come to think of it?

 

Bit of plumbers tape maybe? Silicone would be good but probably too permanent if you ever need it off again.

 

Looks a bit like a bayonet type fitting with those notches - being a lens and designed to focus light in certain ways, I wonder if it has to be on a very specific way to focus the light properly.

try putting it on, if loose take off and rotate a bit and try again, etc. If it’s correct maybe it will be tight.

I don’t know what I’m talking about.

SQUIRREL!

 

Can you see any damage to the base ?
You can compare it to the other side. But don't damage it when taking the lens off.

 

Hi Matt

Worry not, I found getting the lenses off really hard and harder still putting them back on after I'd changed the lenses for Triumphs clear lens kit. First time I tried I couldn't get the lens to stay secure.

My street cup uses the same indicator lenses as your Thruxton and the T100/T120 if we're talking after 2016.

The lenses use a bayonet style lock; as you you've probably found taking them off its about a quarter turn anti clockwise and is really tight, I was worried I'd break the stem getting them off and putting them back.

Putting a new lens back on is the reverse of getting a lens off, so once you've got a lens off look at the "thread" on the edge of the lens and you'll see how it works.

For me and my feeble grip, I found that a small strap wrench (or if you've got one in the kitchen, one of those strap gadgets to loosen stuck jam jars) wrapped around the bottom edge of the lens, gave me the extra leverage I needed to safely twist the lens back on past the locking / catch point. That way I could support the stem while twisting the lens and not snap the whole indicator off.

Triumph were definitely paranoid about losing lenses when they designed that.

Hope that helps.
