Welp, one of my original Fog bulbs finally gave up after 17 years so it's time for new bulbs. I live in the snowy mountain climate of Flagstaff & we are a very dimly lit town due to the dark sky laws. I'm debating if I would be better served in winter with yellows. Just replacing the bulbs, not upgrading or changing housing.
Any thoughrs would be appreciated.

 

Buy some yellows from the online Bezo jungle & try them out. If you don’t like them, send them back.

I have S-V.4 bulbs in 6000k cool white. They are pricey, but super bright, low and wide.

 

I've had white, yellow halogen + I've used super white led.
The yellow were a joy to use in the harsh winter nights when out doing business but they do get old on the eyes quick.
The white halogen are pleasing but defuse into the snow so much I could barely see at times.
The LED are okay but will not melt the snow build up on the lens + will cause a wall of white out during blizzards.
As of yet have not found a good choice lol!
Been doing snow removal professionally for 25 yrs. and have yet to find the goldilocks light.

 

Sorry for the late response as the truck decided the bulb issue wasn't all it wanted to throw at me. Coolant in reservoir decided it likes to boil. The truck has been garaged until I can pressure test & combustion test this weekend. So grateful for both your responses!

As far as the bulbs, I was able to get my "girl" hands pretty easily up to the bulb to remove it. So I'm going to go with both your suggestions & switch the bulbs (wearing clean gloves) when weather conditions warrant. Thank you both again!
