What happens with these is that the lamp just gets brighter as you add more power from the brake switch (unlike a duel filiment bulb, where you have two seperate circuits), and electricity 'leaks' back through the wiring to the sidelight bulb. The answer is to fit a blocking diode in the side light circuit in the rear light. I use cheap ones ment for chinese motorbikes from ebay. These have two spade terminals making fitment easy. Just remember if it dosn't work try connecting the led the other way round!
+1, all to do with the current they require to work, LED`s are not the holy grail of lighting folk think they are in all applications.
