In this guide, we'll help you quickly and easily find the replacement bulb size(s) you need for your 1999, 2000, and 2001 Dodge RAM 1500 (2nd Generation). From the headlights to the brake lights and everything in between.
This truck uses halogens across the entire vehicle. During these three years, Dodge made the RAM 1500 in two versions. One with 2 headlights and another with 4 headlights. Naturally, the bulbs for each are different and so we make the distinction below in our size charts.
This guide covers all sub-models (Regular Cab, Club Cab, and Quad cab), trims (ST, SLT, WS, and Laramie), and drivetrains (rear-wheel drive and four-wheel drive).
We organized all the bulbs into 5 lighting categories with easy-to-read charts. Select any of the categories below to jump right to the bulb size chart you're looking for:
💡 TIP: Did you know that you can upgrade your headlight and fog light bulbs on your RAM 1500? Get up to 300% more light with LED or HID bulbs. Learn more below the size charts!
️⭐ NOTE: This guide only applies to 1999 to 2001 Dodge RAM 1500 with the original factory (OEM) assemblies. If you have aftermarket headlights, fog lights, brake lights, etc. you will need different bulb sizes as per the manufacturer's specifications.
🎯 ACCURACY: If you notice any inaccuracies or missing information, please let us know so we can update the guide. Providing accurate and complete information is important to us and our readers.
🚧 IMPORTANT: Automotive light bulbs are vehicle-specific! Follow this guide, review your owner's manual or contact your dealership to make sure you're buying the right bulbs to avoid fitment issues.
