If your 2007-2013 Toyota Tundra's DRL turn signal bulb sockets are getting hot like the ones pictured above, then you will need to replace the bulbs and the socket itself. The socket part # is 90075-60060 (this part # may change) and runs about $10. You simply open the hood, turn the socket counter clockwise and pull the socket with bulb out. Then just disconnect the socket and replace both.
