RAM ProMaster 1500 Bulb Size By Years
Starting point: I built this bulb size chart after swapping bulbs on my 2018 RAM ProMaster 1500 and realizing how confusing part numbers can be. Think of it as a compact reference to match each lamp location with the correct bulb type, so you don’t guess at the hardware.
Small win and expand scope: First I list the most common interior and exterior bulbs, which gives an immediate confidence boost when replacing a dome or turn signal. Then I broaden to less common lamps like reverse and marker lights, offering a simple mental model for which sockets tend to pair with which outputs.
Refine, validate and quick recap: I test-fit bulbs and cross-checked OEM specs to refine the chart, so it’s grounded in hands-on experience. Quick disclaimer: some links are affiliate links and I may earn a small commission at no extra cost to you, which helps maintain this guide. In short, use this chart as a practical starting point and double-check fit before final purchase.
