There are plenty of great tutorials on the forum about how to do this kind of LED mod, so first off a big thanks to DrunkTarkin, DMGardiner, jasonkc25 and others who have contributed pics and information - I probably wouldn't have tried cutting into my Vic without your examples!
The only special thing about my project was that I managed to pull it off with all reused parts. Reused a battery from another project and the LEDs came from a broken lightsaber toy my son had!
Looking forward to seeing more great conversion ideas from the community.
