Hi, I didn't understand this at first but then i found someone who actaully helped. To make the lights work properly you need to use Vertex mode to select all of the parts of the lights you want to work for each light individually and then go into properties and change the ID from 0 to the corresponding ID provided in this list:
Model ID List for lights:
left headlight (headlight_l) = 1
right headlight (headlight_r) = 2
left taillight (taillight_l) = 3
right taillight (taillight_l) = 4
front left indicator (indicator_lf) = 5
front right indicator (indicator_lr) = 6
rear left indicator (indicator_lr) = 7
rear right indicator (indicator_rr) = 8
left brakelight (brakelight_l) = 9
right brakelight (brakelight_r) = 10
middle brakelight (brakelight_m) = 11
left reverse light (reversinglight_l) = 12
right reverse light (reversinglight_r) = 13
extra light 1 (extralight_1) = 14
extra light 2 (extralight_2) = 15
extra light 3 (extralight_3) = 16
extra light 4 (extralight_4) = 17
