893 Series Mustang Bulbs

Ford Mustang Light Bulb ID

The 893 Series Bulbs are a single filament bulb sealed in a halogen gas filled glass tube. They are found stock in 1994-2004 Mustang GT fog lights,1994-2001 Cobra fog lights, and the 2003 Mach 1 fog lights.

One caution regarding the Mach 1: The H10/9145 or 899 has the same connector, but features a 90 degree angle instead of straight connection. Both bulbs came in the Mach 1, but the 899 is more common.

D3S HID Bulbs

D3s HID Headlight Bulb for S550 Mustangs

The D3S is the bulb the S550 (2015 ) Mustangs use for their headlights. The HID part stands for high intensity discharge. HIDs use a a kind of welding arc and a gas tube. These bulbs take a minute or two to heat up fully for maximum light output. They are more focused than halogens and produce more light.

Unfortunately the fog lights for the S550 are Ford specific assemblies (same with the GT500s). You'll have to convert the stock housings and use an H3 bulb instead.
