2018 RAM 1500 Headlight Bulb Size

The "2018 RAM 1500 Bulb Size Guide" is a meticulous compilation, essential for owners focusing on vehicle lighting. This guide illustrates the use of 16 distinct bulb positions, highlighting the vehicle's comprehensive and versatile lighting arrangement. A notable trend is the use of the 3157R bulb for both brake and tail lights, evidencing a streamlined approach in bulb utilization. Additionally, the 9005 bulb is employed for both high beam and low beam (with projector-type headlights), while the H11 serves the low beam (without projector-type headlights). This pattern of repeated bulb sizes across various positions demonstrates a design aimed at simplicity and efficiency in maintenance.

The 2018 RAM 1500 is a powerhouse of utility and strength, offering robust towing capabilities and a spacious cabin. However, it's not without its drawbacks, including a fuel efficiency that lags behind some competitors and a ride quality that can be stiff at times. Its blend of raw power and practical features make it a solid choice for those who need a reliable workhorse, though it might not be the first pick for drivers prioritizing economy and smoothness on the road.

FAQs

Replacing The Headlight Bulb In A Ram 1500 2018

  1. Access the Headlight Assembly: Open the small clip on the inside of the fender liner to access the back of the headlight assembly.
  2. Release the Headlight Assembly: Push down the white clip inside the fender liner to release the backside of the headlight assembly.
  3. Remove Bolts: Locate and remove two 10mm bolts – one under a cover near the top and another straight down, requiring extensions to reach.
  4. Pull Out the Assembly: After removing the bolts, find two small round grommets that help secure the assembly. Push from the rear to pop it out without scratching anything.
  5. Change the Bulbs: Access the low beam, high beam, and turn signal bulbs. For the low beam (H11 bulb), turn the bulb counterclockwise and pop it out. Disconnect the clip and replace the bulb. Avoid touching halogen bulbs with your fingers, as oil from your skin can shorten their lifespan.
  6. Reinstall the Assembly: Once the new bulb is in place and secure, push the headlight assembly back into position. Make sure it's seated properly without forcing it.
  7. Reattach Bolts and Clip: Reinstall the two 10mm bolts and the clip in the fender liner. Use a small piece of electrical tape on the bolt head to prevent it from falling while installing.
  8. Test the Lights: Before closing everything up, test the lights to ensure they work properly.
  9. Close the Trapdoor: Finally, close the trapdoor in the fender liner and secure it with the small clip.
