What Lighting System Does the 1964 Buick Riviera Have?

The 1964 Buick Riviera 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 Riviera has been available from 1963 to 1964, and the 1964 model falls in the late-generation years.

Can You Put LED Bulbs in a 1964 Buick Riviera?

To upgrade the 1964 Buick Riviera 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 1964 Buick Riviera

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 1964 Riviera 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.

How Long Do 1964 Buick Riviera Headlight Bulbs Last?

Standard halogen headlights on the 1964 Buick Riviera 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 62 years old, the original bulbs on your Riviera 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 1964 Buick Riviera?

The 4000 low beam bulb on the 1964 Buick Riviera 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.

1964 Buick Riviera Headlight FAQ

The 1964 Buick Riviera uses a 4000 LED bulb for the low beam headlights. We recommend upgrading to LED for better visibility.

The high beam bulb size for the 1964 Buick Riviera is H5001 LED.

The 1964 Buick Riviera uses a dual bulb headlight system. This means you have separate bulbs for high and low beams.

Yes, the 1964 Buick Riviera comes with standard halogen bulbs from the factory, but they can be upgraded to LED. You will need a 4000 LED LED conversion kit for the low beams.

Yes, the 1964 Buick Riviera takes a LED Fog Light bulb for the fog light position.

Turn off the vehicle and open the hood. Locate the headlight assembly from behind, remove the dust cover or retaining clip, disconnect the wiring harness, twist the old 4000 LED bulb counter-clockwise to remove it, then insert the new bulb and reassemble. The whole process typically takes 10 to 30 minutes per side depending on accessibility.

LED bulbs used off-road or in auxiliary lights are legal everywhere. For on-road headlight use, legality varies by state. Many states allow LED retrofits as long as the beam pattern meets DOT standards. For the best legal compliance, choose a DOT-approved 4000 LED LED kit that is designed as a direct replacement and produces a proper cutoff pattern without excessive glare.

A pair of halogen 4000 LED bulbs costs $15 to $40, while LED conversion kits run $25 to $60 per pair. If you have a shop do the work, expect an additional $20 to $50 in labor per bulb. Replacing them yourself at home saves the labor cost and usually takes under 30 minutes.

Halogen bulbs produce a warm yellow light (around 3200K), last 500 to 1000 hours, and draw more power. LED bulbs emit a brighter white light (5000-6000K), last 25,000+ hours, and use less energy. LED upgrades for the 4000 LED position are available as direct plug-and-play replacements.
