I just finished doing some minor work on my case (mostly lighting) and I was thinking that it might be pretty cool to get some DIMM lights. I was on pcmods.com and saw some but they are kinda lame (and expensive at $15). I'm looking for something that's a bit more active, like the lights on the front of K.I.T.T. on Knight Rider (or the Cylons facemask on Battlestar Galactica, which you prefer). Anyone seen something like that? If so, do they work with heat spreaders on the DIMMs?

i dunno, but if you were looking for some new ram get ballistix tracer - they have cool black heatspreaders and lights along the top

If he doesnt want to spend $15 on lights, why would he want to get new ram lol. I'd say best option would be make your own lights get some LEDs

Check my sig. I already have Crucial Ballistix.

Gets some led lights and make your own.

I have heard Thermaltake make ram light heatsinks.
