I'm back home from spending the month of October on a remote cape on the Oregon Coast (great place for LED headlights!) - little or no internet coverage. I recently received a message from a customer in Alaska who is putting LED headlights on all of his cars. Thought you might find it interesting.

Hello John...
I've installed the TruckLites on a 356 in final stages of assembly:

Frankly they look stunning and a welcome departure from a typical Wagner or H4 bulb. I've received nothing but compliments on how they look.
As for the purist and concours side to the dilemma, I would put this upgrade in the same realm as seat belts. They are a substantial safety upgrade over H1's and H4's due to the "quality" of light. Couple the LED's with a relay and you got something special. Roads here are not lit up like the greater metropolitan areas so this is a very important aspect of the enjoyment of the car in this neck of the woods.
Finally, the problem I run into is the quality of light one becomes accustomed to. Example: You drive a newer Audi with excellent headlights.

Then you jump into your 356/911:

Glad you are offering this service now. I don't think folks realize what they're missing out on.

I will have some pictures of the TruckLites, Pilots and Speakers mounted on a 911 in a day or two - and some shots of the light patterns against a wall.
Cheers,
John
