The LED topic is a recurring one -- here's a good comparison of headlight choices from Jalopnik: http://thegarage.jalopnik.com/should-you-swap-your-headlight-bulbs-for-leds-1728026383

Unlike the halogen bulbs, the LED replacements come in a variety of powers. High power LEDs almost always come with a fan cooled heat sink. Since the subject units had some unusual heat radiators, I would question just how much power they had.

 

Getting a high power LED lamp, heat sink with fan, and ballast to fit into a 7 inch reflector and inside our headlight bucket is problematic. There are 7" LED reflector units that are street legal with a $400+ price tag.    

When they can make an LED or HID that doesn't blind on coming drivers then I'll consider them.

Hands up, anyone not been blinded by these toys?
