I went and changed EVERY bulb in the tahoe to LED, The interior lights are 9LED per bulb, and the outside are 32 LED per bulb. I have 10k HID for Low Beams and 12k Hid for High Beams but havent had a chance to install yet . I Changed my blinker lights to the reverse lights and there bright as hell when i put the blinker on at night. Will update tonight when it gets dark.
