LED lights not working on a piaggio nrg power?

i bought these LED lights from halfords and i fitted them into the front side lights of my ped, they fit fine as i brought the original bulbs into the shop, now less than a month there not fully working. if i take it out of the socket (with it still connected) and cup my hands around the led i can just see a blue tinge. but no way as bright as they were at first. the light is made out of 4 small LEDs, do you think maybe some have blown ( if they can) or if something else has damaged them? cheers

1. LEDs have a 10 year life span on average. They do not blow out but rather burn out (over a period of 10 years.) The burning part of an LED is half the size of a grain of salt. If you have any way to test the ohms of the circuit that's where I would begin. If you have another piaggio handy test the same circuit's ohms and then compare to yours. You can also find the normal operating range for the circuit's resistance in a service manual (not an owners manual.) They may be receiving less power due to increased resistance in the circuit.
