It really bugs me that on my 110 the heater controls aren't lit.

I understand TD5 on ones are lit.

Is it possible to fit the lighting bits from the TD5 controls to my ones to light them?

To be fair you can hardly miss them tho lol

The wiring inside the TD5 instrument cluster is a bit different than on earlier models so it's probably not a straight swap with anything. Having said that, it shouldn't be too hard to locate the wires to the existing instrument bulbs and splice in an extra bit of wire and a miniature bulb or two. There's a lot of plastic round that area so they'll want an earth to the bulkhead too for best results. Oh, and of course make sure that the bits of trim round the lever actually have translucent bits for the light to come through as they do on later models.

You could always add one of those small LED strips of eBay and wire it up so it illumanates whn you have your lights on. The cost 0.99p. Very effective.

I like the LED strip light idea.

I'll look into that.
