Here are the results. Halogen on the right. Super bright incandescent from Sacramento Vintage Ford on the left.
Indeed, the incandescent is just as bright as the halogen with even some other advantages: 1) They're less than 1/3 the cost - $3.95 compared to $15.50 for the halogen. 2) They are conventional filament location just like standard bulbs rather than the weird double bulb configuration of the halogen. The advantage of that is that the filaments actually line up with my blue dot and shine straight through them instead of being off to the side like the halogens. That's why the left light looks so much bluer. I really like that. 3) Hopefully they'll last longer. But, even if they only lasted 1/2 as long they'd still be cheaper because they're less than 1/3 the cost.
For my application of stock 6 volt and blue dot lenses, there's nothing better. I'm very pleased. Thanks again
