LED Replacement Bulbs for VS Fog Lamps

Those Halogen bulbs and their replacements have pigtails/wires on the bulb. That metal bulb holder that the bulb was soldered to is part of the bulb.

It looks like an H3 to me. Check these out, specs and measurements on page:

Thanks Danny!

The "Focusing" part of those bulbs is a way of moving the light source closer to or farther away from the lens.  As you move it in or out, the light pattern ahead will go from a wide floodlight pattern (used in fog lights) to a focused spotlight pattern (used in driving lights).  They may look great on your first install, or you can play with them til you get the pattern you like best.

How do you move them in and out? That little round plate attached to the base of the bulb is screwed into the housing and I don’t see how to move it.

The base stays put while the lightbulb itself is allowed to move with that SuperBrite LED bulb.  That way it can be used in both a running light and a fog light.

I agree H3, they are so cheap why do you want to change them to LED's?  Especially if you have relays on them.  I have marchalls that I converted to H3 from Tungsten  because they are much easier to handle then tungsten bulbs that burn out all the time.   BTW the H3 have been there for over 3 years with no issues.  Kiss method works for me as the lense must be focused and LED's unless made to pattern itself after the original bulb reacts differently with light spread.  just saying.
