I installed my interior LEDs last night. Made a mistake and overlooked the rear cargo light so will put in another order if I go DRLs and switchbacks. I chose the 6K 29mm
festoons from VLED and their 6K
194 bulbs for the license plate lights. Today I'll be installing the 5K
H11 fogs. VLED has the 921 bulbs for the rear backup lights on backorder.
I have the HID-equipped Grand Touring model and felt the 5K fogs would match up better with the 4300K HIDs.
For contrast, I left one of the vanity lights stock and can't believe the difference! The 6K lights produce a very clean, white light making the stock incandescent look odd. I plan on eventually retrofitting the DRLs.
While the interiour LEDs do dim and fade out per the control unit, I do notice a slight flicker just before they start the fade process. Perhaps I'll grow into it but it is noticeable.
UPDATE: Just completed installing the H11 5K fog lights. They went in without a hassle - just learn how much of the plastic panels you have to loosen/remove and have skinny forearms like myself - I do play the pipes but don't weigh near as much as Fat Bastard featured in my avatar.
The 5K choice appears to be a good one as the fogs and HID headlights are now approximately the same color temp. I didn't have to fiddle with the metal shields since the VLED H11 bulbs fit right in. Unfortunate that I do lose the 2 forward-firing LEDs behind the convex lens on the bulb but the 8 side-firing LEDs appear to be adequate. I did a compare after installing the first but didn't take a photo since I have to be somewhere very soon.
UPDATE2: Installed the 6K P13 DRLs this afternoon. Look pretty nice - definitely noticeable from the warmer DRLs you see all the time.
UPDATE3: Installed the 6K 921 backup LEDs yesterday. They had been on backorder. Had the car in the garage, put it in reverse w/power switch on. My neighbor, who is a car technician, had just pulled into his driveway and saw my backups on. He came over to say how great they looked.
