led covers

[Phil6N]

Does anyone know where you can get little rubber led cover/caps from? Havent got a pic, but anyone who has taken apart switches like e/windows or rear window heater on a mk4 will know that i mean.
Iv searched the net for hours with no luck, someone must make them cause they come standard on the car.
Iv tryed maplins but they only do these plastic cap things that dont work that good.
Cheers
