What is the low beam headlight bulb size for a 2017 Ram ProMaster 3500?

The 2017 RAM ProMaster 3500 uses a H7 bulb for the low beam headlights. We recommend upgrading to LED for better visibility.

What is the high beam headlight bulb size for a 2017 Ram ProMaster 3500?

The high beam bulb size for the 2017 RAM ProMaster 3500 is H7.

Why are my 2017 Ram ProMaster 3500 headlights dim?

Dim headlights on a 2017 RAM ProMaster 3500 can be caused by aging halogen bulbs, which lose brightness over time, or oxidation (cloudiness) on the plastic headlight lenses. Upgrading to a H7 LED conversion kit can provide a significantly brighter and whiter light output.

Which bulb fits the 2017 Ram ProMaster 3500 fog light?

The 2017 RAM ProMaster 3500 uses a H11 bulb for the fog light position.

Is the 2017 Ram ProMaster 3500 single or dual beam?

The 2017 RAM ProMaster 3500 uses a single bulb (dual filament) headlight system. This means one bulb controls both high and low beams.

Can I install LED bulbs on my 2017 Ram ProMaster 3500?

Yes, the 2017 RAM ProMaster 3500 comes with standard halogen bulbs from the factory, but they can be upgraded to LED. You will need a H7 LED conversion kit for the low beams.

Does the 2017 Ram ProMaster 3500 have fog lights?

Yes, the 2017 RAM ProMaster 3500 takes a H11 bulb for the fog light position.

Did the 2017 Ram ProMaster 3500 change headlight bulb sizes from the previous year?

Yes — the 2017 RAM ProMaster 3500 uses different bulb sizes than the 2016 model. The 2017 generation introduced this bulb configuration.

Is the 2017 Ram ProMaster 3500 the first or last year to use H7 bulbs?

The 2017 RAM ProMaster 3500 is the only year in the 2017 generation to use the H7 bulb for the low beam headlight.

How do I change the headlight on a 2017 Ram ProMaster 3500?

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 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.

Are LED headlights legal for a 2017 Ram ProMaster 3500?

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 kit that is designed as a direct replacement and produces a proper cutoff pattern without excessive glare.

How much does it cost to replace 2017 Ram ProMaster 3500 headlights?

A pair of halogen H7 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.

What is the difference between halogen and LED for a 2017 Ram ProMaster 3500?

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 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.

The 2017 RAM ProMaster 3500 has a unique bulb configuration not shared with adjacent model years.

What Lighting System Does the 2017 RAM ProMaster 3500 Have?

When it comes to nighttime visibility, the 2017 RAM ProMaster 3500 relies on an arrangement of 8 specialized bulbs. It features a comprehensive lighting system powered by a halogen-based setup where a single H7 dual-filament bulb handles both low and high beam duties within the same reflector. Note that RAM vehicles typically feature a CANbus electrical monitor that checks for specific bulb resistance.

LED Flicker Warning

This vehicle is known to use a CANbus system. Installing standard LEDs may cause flickering.

Use a CANbus decoder.

Can You Put LED Bulbs in a 2017 RAM ProMaster 3500?

For a RAM built for the road and trail, LED upgrades provide the high-contrast lighting needed for better obstacle detection. Since your ProMaster 3500 uses a single H7 bulb for both high and low beams, ensure your chosen LED kit is "dual-beam" compatible. This allows the LED circuitry to mimic the two-filament design of the original halogen bulb. Because RAM utilizes a CANbus system, standard LED bulbs may cause "bulb out" errors on your dashboard. Always opt for "Error-Free" or CANbus-ready kits which include the necessary resistors. Don't forget the H11 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
