Sorry if this has been asked before but what sort of length T10 and T5 bulbs will fit the IS200 dash? I've got a couple of bulbs failed on mine (one on the speedo and one on the heated seat switch, when the lights are on not when it is in use - anyone know what bulb this takes?). I've tried looking through many posts and also other sources but I cannot seem to get any definitive answers. Thanks in advance for your help
