I've got the L691s on mine. Red and yellow on the back and clear on the front. I'm running LED globes all round and they are super bright.

I reckon it wouldn't be hard to put an LED globe in those rectangular Lucas lights. You would have to change the bulb mounting a bit because the LEDs are very directional.

As for turn indicators, how about some of those reversing lights you've got but fitted with orange LEDs. They could be placed in the rear panel at the same height as the reversing lights but spaced out wider.

Cheers
