See what the working voltage of the lamp is (often it's 6.3 or 12.6 V). Next measure the voltage you're getting at the lamp socket. I'm betting it's going to be at, or over the working voltage of the lamp. The lamp spec. will also give you its current draw, in mA. Then calculate the value of resister needed to drop the voltage (likely a volt or two), using Ohm's law.
Note that you're going to have to do the same measurements, calculations, and soldering if you switch to an LED, so the lamp fix is actually a bit easier.
It sounds more complicated than it is. When you're ready to do it, post a request, or email me and I'll be happy to walk you through it if you need assistance.
