What Lighting System Does the 2016 RAM Promaster 3500 Have?

The 2016 RAM Promaster 3500 features an extensive lighting system with 12 bulb positions. It uses halogen technology with a single H7 LED dual-filament bulb handling both low and high beams. The Promaster 3500 has been available from 2014 to 2016, and the 2016 model falls in the late-generation years.

Can You Put LED Bulbs in a 2016 RAM Promaster 3500?

Upgrading the 2016 RAM Promaster 3500 to LED headlights is straightforward since it uses a single H7 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 H7 LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. For the fog lights, a H11 LED LED bulb provides a clean white output that pairs well with LED headlights.

How to Replace Bulbs on a 2016 RAM Promaster 3500

The H7 bulb uses a spring clip or wire retainer that holds the bulb in the socket. To remove the old bulb, disconnect the wiring harness first, then twist the bulb counter-clockwise and pull it out. On the 2016 Promaster 3500, you will likely encounter rubber dust covers behind the headlight housing. These pull off by hand or unscrew depending on the design. Allow about 15 to 20 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 H11 LED fog light socket.

How Long Do 2016 RAM Promaster 3500 Headlight Bulbs Last?

Standard halogen headlights on the 2016 RAM Promaster 3500 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 10 years old, the original bulbs on your Promaster 3500 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 2016 RAM Promaster 3500?

The H7 low beam bulb on the 2016 RAM Promaster 3500 is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact H7 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.

2016 RAM Promaster 3500 Headlight FAQ

The high beam bulb size for the 2016 RAM Promaster 3500 is H7 LED.

Yes, the 2016 RAM Promaster 3500 takes a H11 LED 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 H7 LED bulb counter-clockwise to remove it, then insert the new bulb and reassemble. Note: RAM vehicles use a CANbus system, so LED replacements may need an anti-flicker decoder. 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 H7 LED LED kit that is designed as a direct replacement and produces a proper cutoff pattern without excessive glare.

A pair of halogen H7 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 H7 LED position are available as direct plug-and-play replacements. Since the RAM uses CANbus monitoring, choose a CANbus-compatible LED kit to avoid dashboard errors.
