Blue glass = less light output

I'd go for XtraVision or something like that. Anything with blue glass is a waste of time.

I saw these the other day. Sylvania's blue coating on their "premium" bulbs gets thicker and thicker with every new iteration.

what do you guys think of yellow bulbs for foglights?

I actually like them.

Yellow offered by today's bulbs offer no advantage.

Why? Today's "bulbs" are only as good as the housing they're put in, many of which are still a sorry excuse for a headlight. Personally, I've used 3000k (not very yellow, but kinda) bulbs in fog lamps before and it does help in wet/foggy conditions, especially if your car has decent fog lamps they do what they're supposed to do: light directly in front of the car, and the sides. Personally, if you go with yellow fog light bulbs, go with 2500K. Nice yellow color

of course, the yellow coating on the bulb will reduce output, but fog lamps aren't the primary lighting source anyhow, so I don't see it as a problem.

Blech. Those are basic Ebay blue bulbs repackaged in a Sylvania box.

The Xtravision H13's in the Cruze and GE motorsports DOT-approved H4's in the Fit both offer fine lighting for not a lot of dough.

kinda,

a bulbs output measured by kelvin's temp scale and lumens.....

so what this means is a fog light bulbs true color temp. should possibly look yellow but the bulb itself should not be tinted yellow.

the color temp is dictated by the light itself not the coating on the bulb.
If the bulb is "tinted' than it's junk.

your best light output happens between 3000-5000 Kelvins, blue does not equal bright infact you loose usable lumens over 5000k

At one time France require yellow headlights, etc. Those bulbs were "Select Yellow". The glass was actually tinted, not coated, to provide the yellow color. The heavy metal cadmium provided the tint. This can no longer be used so any yellow bulb you purchase today is coated, thus providing less light output and the color is far from Select Yellow.

Research has not supported the former French position that yellow provided a significant benefit. Likely still better than the trend toward blue tinted bulbs.
