For Alphard 30 and Vellfire 30 This is an aluminum seat heater dial. Compatible with both early and late models. Illumination type! Although it's a small part, it's in a place that's easily seen, so it gives a more luxurious feel than the original plastic dial! Installation is easy. Just pull out the original dial and insert the aluminum dial! Before removing the original dial, set the dial markings to the OFF position and then start the work!
