What Lighting System Does the 1971 Nissan 510 Have?
The 1971 Nissan 510 features an extensive lighting system with 12 bulb positions. It uses halogen technology with 4000 LED low beams and H5001 LED high beams in a dual-bulb configuration. The 510 has been available from 1968 to 1973, and the 1971 model falls in the mid-generation years.
Can You Put LED Bulbs in a 1971 Nissan 510?
To upgrade the 1971 Nissan 510 headlights to LED, you will need a 4000 LED LED kit for the low beams and a H5001 LED LED kit for the high beams. Start with the low beams since they are used most often and have the biggest impact on nighttime visibility. 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 1971 Nissan 510
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 1971 510 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 1971 Nissan 510 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 55 years old, the original bulbs on your 510 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 1971 Nissan 510?
The 4000 low beam bulb on the 1971 Nissan 510 is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact 4000 size. Using the wrong bulb size can cause improper beam patterns that reduce your visibility and blind other drivers. It can also cause overheating inside the headlight housing, potentially warping the plastic lens or reflector. Always verify the bulb number before purchasing.
