I'll 2nd the LED vote...
My signature shows my blue parklight LEDs. These are an LED with a 'wedge' type base, so they fit if they were a 'real' wedge type globe.
I purchased Phillip's "Diamond Vison" globes for my main beam (bloody expensive $160AUD+ for a pair!!), and the packaging came with 2 'blue' wedge globes. These weren't blue enough in my opinion, hence the LEDs.
I could only find one set on ebay worldwide, but they don't appear to come with the wedge bulbs too:
