YES we replaced ours with these from AMAZON and they have worked well for 2.5 years. These bulbs replaced the tradtional bulbs that are in the lights throughout the interior and the outdoor light on the side. As for the circular lamp fixture in the rear I picked up a rectangular one at Camper World that has two settings and it was simple to switch out and gives us lots of light.
Definately a good idea to switch out bulbs.
Do pay attention to color and get what you prefer.
Our 2002 Dodge RT 190 is also original inside and we just use it. It works well and I am not intereseted in messing around with it. However the light blue carpets are the one thing I'd love to get rid of as they get dirty too easily, stain too.
Safe travels.
