In November 2018 we saw a release of two game changing LED kits - X7 and GT. Both kits are amazing and offer different features - X7 is a canbus LED kit, GT is non-canbus; Both use high speed fans to cool the led bulbs; GT uses XHP70 CREE LEDs while the X7 uses Samsung CSP LEDs; and Both are 90W kits with 45W per bulb. On direct light meter tests, both kits performed nearly the same, with only 200LUX difference. Suggested use for both X7 and GT series LED kits is for headlights. It is because of the cooling fans that we do not recommend them for fog light use. The exception would be where the fog lights are completely closed off from the wheel wells and the bottom of the front of the vehicle.
