Well they sound good.. from a top rated seller too.

New Orange Electronic Tire Pressure Monitoring Sensor (TPMS) # SC90AC | eBay

Can most local tire shops activate these? My TPMS light has decided to shine now with full pressure on the tires. Funny thing too.. fuel light makes random appearances when I'm low on gas. Noticed it didn't light up switching the ignition to on. Thumped the area of light and behold.. let there be light.. lol. Reading across a bunch of threads.. are these led or bulb type?
