Hi, (I know this is a few weeks old, but thought I'd leave the info for future) Yes this problem has come up quite a few times. Why Chrysler decided to directly solder incandescent bulbs onto the circuit board I'll never know! I've done this repair on mine and a few others with LED replacements, they're tricky to do and the tracks can come off when you're soldering on the old Chrysler board but it's do-able. I made a good find on ebay a while back, model train enthusiasts use small LED strips to light up carriages, etc, and they are ideal for this application: http://www.ebay.co.uk/itm/QUALITY-9v-12v-DC-3528-LED-SUPAFLEX-LIGHTING-STRIP-MODEL-RAILWAY-N-OO-HO-O-GAUGE/151025926614?ssPageName=STRK%3AMEBIDX%3AIT&var=450232359825&_trksid=p2060353.m1438.l2649 So those might do what you want, just solder in place and as Penguin2007 says make sure you test and get polarity correct. There are no markings for + or - on the little board you remove from the car so I ended up doing it the hard way, get your multimeter and test it whilst connected to be sure.
