Thought I'd give an update. The Zevo 3157R's work very well in the taillights, brighter and a bit more more red (even though it doesn't *look* more red in the attached pics). There is a very noticeable brightness difference between running light and brake light as well. I'd already picked up some inexpensive LED 921R's
a while back for the third brake light. In the pics: Driver's side = Zevo LED
Their 3157A's are not so hot in the front, though. They were bright when viewed from the front, but the scatter (and therefore side visibility) just wasn't there. A 360° design is needed due to the shape of the reflectors. The Zevo was also too yellow for my taste. I need to find a bulb that is more orange-amber than yellow-amber.
Zevos in the reverse lights failed miserably. They were a lot whiter, but the incandescents throw more light, and I'm going to stick with them. Photo is attached. I'll let you guess which is which.
The EP27 flasher I bought flashed *much* more quickly than the stock one w/ OEM bulbs. I found that this flasher, though, can be modified with a tantalum capacitor to slow the flash rate. The video below shows a comparison of OEM, EP27 stock, and EP27 with a 1uF capacitor added.
The 1uF cap gives a nice rate for the LED's, but is still too fast for the (still currently) incandescent bulbs up front. I've procured some 2.2uF caps, and may try one to see how it looks.
Hope this info is helpful to someone else considering converting.
