Is there a LED lighting set to give that dim 1980s look?
Go for soft, or warm white bulbs, or, if you really like to torture yourself, find some 6V grain of rice incandescent bulbs. I've used them before and look the part, because they are the part!
Hi Joss - if you are in the UK (by your user name I'm guessing so), then there is an ebay seller called Model Lighting Solutions who can make up looms with any combination of LEDs - sizes/colours etc. including a softer 'vintage' glow version... they made me one for my Tam-Mater build a while ago - the headlight (and rear work light) were the vintage glow (sort of yellowy white) and the tail lamps were regular red.
I run the rice bulbs in my 55, and the warm leds in my 62. The bulbs definitely have more character, the only downside is they eat a little more power. Fine if run off the battery, but I use a separate 9 volt so I can run the lights on the shelf without connecting the battery. But to complete "the look" they are worth the trouble.
