What Lighting System Does the 2021 RAM ProMaster City Have?
When it comes to nighttime visibility, the 2021 RAM ProMaster City relies on an arrangement of 5 specialized bulbs. It features a standard lighting system powered by a dual-bulb halogen configuration using separate H11 low beam and 9005 high beam bulbs for precise light distribution. 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.
Can You Put LED Bulbs in a 2021 RAM ProMaster City?
For a RAM built for the road and trail, LED upgrades provide the high-contrast lighting needed for better obstacle detection. We recommend starting your upgrade with the H11 low beams, as they see the most use. Adding a matching 9005 LED kit later will complete the look and ensure consistent lighting performance. 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.
