For the 2005 Nissan Titan, the supplied fitment data lists a 9005 bulb for the high-beam headlight. No low-beam bulb is specified in the available data, so confirm the low-beam socket on the vehicle before ordering. If equipped, the fog lights use an 899 bulb.
Other useful exterior replacements include 3157A for the front turn signals and parking lights, 194NA for the front side markers, and 3156 for the rear turn signals. The brake and tail lights use 3157R. Reverse lights and the center stop light both use 921 bulbs.
For lighting around the cabin, the dome and map lights use DE3175. The door mirror uses 906, while the glove-box and step lights use 158. License-plate fitment is listed as either 168 or 917, so check the existing bulb and socket. No headlight-type or configuration-specific variation is provided in the supplied fitment data.
