The project for this evening was replacing the low beam bulbs and lenses in the S4’s headlights.

I picked up a pair of the TSR-X lenses from The Retrofit Source and a pair of Philips X-treme Vision 4800K bulbs from HID Concept.

There’s a nice DIY for the lens swap on Audizine.

The swap took a couple of hours with the second headlight going faster than the first as I applied what I learned from the first to the second.

Tomorrow I’ll have the chance to take the S4 out at night and see how the new setup looks.
