I also drive my cars and have little interest in getting a plastic trophy. As such, I have installed radial tires on both my Model A roadster and my 1954 Ford Sunliner. The ride is much safer, in my opinion and does not take away from the 'feel' of driving an antique car. I draw the line at modern radials, since I think the look of the lower profile just does not go with the older cars. Instead, I chose the radials that look like bias ply tires, but that was my choice. It's like oil, I just would not run my older cars with oil of the 30's (even if I could find some). For headlights, I just installed a set of 7 " LED lamps on the 54 that I purchased from Rodtiques. These have a sealed beam body with a replaceable LED bulb. The run on 12 volt minus ground, but you can get an inverter to change the source from 6 volt plus ground. They are outstanding and draw far less current than the halogen bulbs. I think you would be more than satisfied with these replacements.
