If your specific Dodge Ram uses 4 x headlight bulb system, then H11 bulbs are used as factory low beams (which can be confirmed within its Owners Manual - under its light bulb replacement details section). If H11 bulbs, I would simply replace the factory low wattage H11 with the modified "off the shelf" higher wattage H9 bulb. Simply modify the steel base of the bulb and install. Then, adjust the aim of the new bulbs. Being a little brighter, you may have to point their aim slightly downward. Especially while towing - when a Tow Vehicle has natural rear sag (which points all front lights upwards).
For more details about H11, H9 and other bulb details, surf details within:

Note: To modify the H9 bulb's steel base, I use a rotory tool like:

Always use a dry tissue between fingers and glass. Thus, no natural oil is transfered from your fingers to the light bulb glass.
Hope this helps....
