ouch, I put the LED bulbs in the old style 3xxx bulb fixture as advertised and they work great.Lucky you have a unit with replaceable bulbs. A .90 cent bulb is far less expensive than having to replace LED fixtures when the LED's fail.
My 2012 has exterior tail/clearance lights that are LED. When they fail, have to replace the entire light fixture.
So far, have replaced 2 of the clearance lights and one of the tail/stop light fixtures which far exceed the cost of replacing a burned out bulb or 3!
