For the 2004 Chevrolet Colorado, the low-beam headlight uses an H6054 bulb. High-beam fitment is listed as either 9005 or H6054, so check the existing headlight housing and original bulb before ordering. The high-beam choice may vary by the vehicle’s headlight configuration.
Fog-light fitment also requires comparison with the original bulb. The listed options are 9045, H11 LED, and H16 LED, with H11 LED and H16 LED shown as alternate options. Do not assume these are interchangeable without confirming the original fog-light socket.
Useful exterior bulb sizes include 3757A for the front turn signal and parking light, 3057 for the rear turn signal and reverse light, and 3057R for the brake and tail lights. The center stop light and trunk light use 912, while the daytime running light uses 4157NA. License-plate lighting is listed as either 2825 or 98. Interior lighting includes 561 for the dome light and 211-2 for the map light.
