Got my LED's installed today. Went with the green bulbs and left the blue filters in place. Don't know if any body else had this problem, but the LED bulbs wouldn't fit in the light bar hole. Had to drill it out with a 7/16" bit which also helped make a good ground to the light socket. I expanded the keepers on the sockets and it worked out OK.
I first thought I would have to drill mine out also. But I used dielectric grease on the panel and they finally slipped in. I also used green bulbs with the blue filter.
Btw, be very careful and make sure the bulb socket does not have
any corrosion and put dielectric grease on the bulb. I twisted the base loose from one because it didn't want to twist into the socket.
