2005 rav 4 interior light wont come on when opening drivers door but can switch it on manually is it a double bulb?

The interior light in your 2005 RAV4 may not come on when the driver's door is opened due to a faulty door switch or a wiring issue, rather than a double bulb. The light typically has one bulb that serves both manual and automatic functions. Check the door switch for any obstructions or damage, as it is responsible for triggering the light when the door is opened. If the switch is functioning properly, you may need to inspect the wiring or consult a professional for further diagnosis.
