The 1974 Nissan 260Z features an extensive lighting system with 11 bulb positions. It uses halogen technology with a single 6014 LED dual-filament bulb handling both low and high beams. The 260Z has been available from 1974 to 1975, and the 1974 model falls in the early-generation years.
Can You Put LED Bulbs in a 1974 Nissan 260Z?
Upgrading the 1974 Nissan 260Z to LED headlights is straightforward since it uses a single 6014 LED dual-filament bulb for both low and high beams. You only need one pair of LED bulbs to upgrade both functions. Look for a 6014 LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. For the fog lights, a LED Fog Light LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 1974 Nissan 260Z
To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. Older model years like the 1974 260Z typically offer easy access to the headlight bulbs from behind the headlight assembly under the hood. Most owners can complete the swap in under 10 minutes per side. When installing the new bulb, avoid touching the glass with bare fingers. Skin oils create hot spots that shorten bulb life. Wear clean gloves or handle the bulb by its plastic base only. The fog lights are accessed from underneath the front bumper. You may need to remove a few plastic clips or screws from the fender liner to reach the LED Fog Light fog light socket.

Standard halogen headlights on the 1974 Nissan 260Z have an expected lifespan of 500 to 1,000 hours, which works out to roughly 2 to 3 years of normal use. Signs of a failing halogen bulb include noticeably dimmer output, a yellowish tint compared to the other headlight, or intermittent flickering. At 52 years old, the original bulbs on your 260Z are likely overdue for replacement. Even if they still illuminate, reduced brightness significantly impacts nighttime safety. When one headlight burns out, replace both sides at the same time. Bulbs from the same batch age at similar rates, and mismatched brightness is distracting to oncoming drivers.
What Bulbs Are Compatible with the 1974 Nissan 260Z?
The 6014 low beam bulb on the 1974 Nissan 260Z is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact 6014 size.
