Default Whats the difference between the 3157 and the 4157 bulb?

I'm going to be swapping out my fog bulbs, drl and turn signals tomorrow and I've got a hazard switch on the way. I'm going to go with the brighter 50W fogs and I'd just like to know the difference between these two bulbs...?

I think they'll both work and I've heard mixed info as to which is actually the stock replacement.

If there is one that is brighter, that's the one I'd like to match the fogs/headlights.

Thanks for any advice,

Donnie

Thanks Lucky,

So if I'm reading that right...there is no difference?...edit: after scrolling down, I can't figure out the difference but it seems like they're both pretty much the same.

Dimensionally they look to be the same. Depending on which 4157 you get, it will draw more current, and give off more light.

Thanks man. I'm assuming that the 4157NAK is the one to get? If anyone is running these with success...lemme know.

The current shouldn't be too much more I wouldn't think from such a small bulb...

Or actually, aren't the 3157 the OEM stock replacement bulb equivalent?

I'm gonna search around some more...

Alright, I've got it. 4157NA is the bulb to use.

Take care guys and thank you Lucky,

Donnie

I just pulled one. It's a 4157NA. NOT 4157.

As per this post, I bought a pack of 3157's and they may work but they are clear. The 4157NA is amber.

Any bulb with the "NA" suffix has amber colored glass (as opposed to painted yellow). The "K" refers to Krypton gas used internally giving longer filament/bulb life.

4157 in general is supposed to be a longer life bulb which is a good thing for use as the DRL since the signal filament is on constantly for the DRL's compared to a 3157 in most applications where it only comes on during braking or signalling. However, there are so many variations of both that it's hard to know which one is better so if you see either one with some kind of "long life" description it'd work too.

Default I've been using 50 W 885s for fogs for years MUCH BRIGHTER

For a couple bucks use the 885s instead of 889 or 893s in your fogs.
Use them all the time and they are almost as bright as headlights.
Reaim the fogs parked about 20 feet from a light surface like a garage door with the low beam headlights on.

Had one fog light go out the other day. Are they hard to reaim if I decide to replace both?
