if u look at the pic you'll see red (altho theyre actually silver in the pic) LED's at the top and bottom of the light (2 rows top and 2 rows bottom).
the ones on the bottom are ur fog lights (mine are only wired up so one works tho not both sides which u can have) the ones on the top are ur brake lights and both sides should light up when u put ur brakes on.
the 2 rows of red led's (coloured red in the pic) one row above and one row below the lights in the middle are your lights. so when u put ur lights on it is these 2 rows that come on.
then the ones in the middle. u got the red circular reflector in the middle then the one on the outside i believe is ur indicator (not pictured but these would have orange bulbs in as the lense is clear) and the ones on the inside are ur reverse lights again u can have them both wired up but i only have the one working.
only have one reverse and one fog is fine it will pass the mot but u can wire up both sides to work if u want.
so to sum up the lights are: (the 2 sides are just mirror images of each other)
top 2 rows of leds are ur break lights.
the one single row (red led's) after that is ur normal back lights.
the next is normal bulbs inside light i think is reverse and then u got the reflector then the one on the outside is indicator.
then another line (red led's) again are ur normal back lights.
then the 2 rows of leds below that at the bottom are ur fog lights.
hope this helps... any more info i will see wat i can do......
