My driver side low beam is blown out, I don't think I need to replace the whole assembly and would like to save some money and just replace the bulb. Can I just replace the low beam bulb? I tore into it and it looks like I will have to take the plastic bumper off to access the assembly better? or can I just replace the bulb with the assembly in place? I have some health issues that make it hard to do some of this work like I used to do on all my cars. Any help would be appreciated. I see on Ebay they advertise just bulbs for these trucks but how do you get the bulbs in there, it looks very tight to get too. I did take the rubber protector off and took a look in there? Again it would be nice to just replace a single bulb as to save me some money. Dam these things are a compact design, headlight needs alot of things removed to access it wow.
