I recently converted all bulbs on my '06 Sprint ST, except the H7 headlamps, to LED. The OEM tail light & brake light assembly is already LED so I didn't have to change that. This conversion included the front parking light, front and rear turn signals, tag light, and the addition of HyperLites. The LED bulbs chosen for the front parking light and front turn signals fit without making any modifications whatsoever to the sockets or housings. I used a Lockhart-Phillips tag frame which inculded LED turn signals and added black LED tag bolts to light the tag. The HyperLites chosen to enhance brake lighting were 16-element units. First, some pics to show some key features:

FRONT PARKING LIGHT:
HYPERLITES, L-P TAG FRAME, LED TAG BOLTS:
Here is a list of items used:
Black LED tag bolts (Custom Dynamics, part # TB01B)
Lockhart-Philips Stealth License Frame Amber (Cycle Gear, part # LOC 122-0060)
HyperLites (H&R Enterprises, part # HLU32-R)
Front Parking Lamps (superbrightleds.com, part # WLED-WW5)
Front Turn Signals (superbrightleds.com, part # 921-A12)
LED Bulb Flasher Unit (superbrightleds.com, part # CF13GL-02)
While I was at it, I also replaced the OEM H7 head light bulbs with Osram NightBreakers from Autosave Components in the UK. The part number on those bulbs was: OSRO499NBR
Overall, the conversion to LED was fairly easy and the bulbs are definitely an upgrade to the OEM lighting. I should point out that the front turn signal LED bulbs are more directional than the stock bulbs and do not utilize the reflector housing as well as the stock bulbs. Still, they are quite bright and show up well, especially from the side. --Ken B.
