Yokomo makes a kit, but, as Yokomo is, it's a little pricey, but they are active (they flash). Varad (www.RCNeon.com) also makes many RC led products (light kits, underbody lighting, lisence playe lighting, etc.) and they're quite good quality, my only complaint is that they plug in to a 9 V battery which is a huge hassle to set up in the body, but if any of you could change that, I'm all ears. Tamiya also makes some light sets, but I haven't had any experience with them.
