I just installed some LEDs to replace the 18 watt malibu lights I had been using in the driving lights. Thought I would share the results.
Ordered the WHP15 from superbrightleds.com (I'm not being paid, although I wouldn't mind it ) I chose the cool white color. It is a 194/168 socket bulb.
They initially when I installed them they weren't lighting up. Problem was the leads weren't long enough. So I did a little lengthening with some copper wire.
After installing them they are looking a lot brighter than the malibu lights they replaced, but it is hard to say without seeing them at night. I'll post an update after I see how they are at night.
(the headlights are silver stars for reference)
