Kristopher is right about the focus issue, which is what I was alluding to in my post. The brightest bulbs in the world are junk without the proper reflector in the proper position. You can play with this for yourself if you go in a dark room with mag-lite type flashlight. Screw the end in and out, then take it off all together and see the differences in the output.
Back when I had my pop up car I looked at this too but it's just not going to be easy without serious surgery because the trim pieces and the hood on the lights cover up most of the top of the reflector which is what puts the light down on the road where you need it.
I can't remember what the lights work like stock but I put a dual filament orange bulb in the signal light location, then wired it so it was on all the time. Then I had the whole light cluster lit up, I also put orange bulbs in the corner lights in both spots. I think it looked pretty good. One thing I did consider was that orange signal light repair tape, on the inside of the light cluster nearest the headlight itself, that would turn the headlight's light orange when the lights are down so the whole cluster would light up orange. I never did it tho because I was worried about it looking dumb with the headlight part staying orange when the car was shut off.
