Well, I've gotten ideas from people here, and got great results. So, I thought I'd share! These are the LEDs I installed. I used the Ozniums like Impulse. I got the dimming (and flashing) remote from them, too. All together, under $200 with great shipping and super high quality! These photos are with the dimmer on the brightest setting, and were taken in dark, under the cover, so in almost complete darkness. The brightness seems perfect. Not too bright, easy to see things, and see where you are walking. The dimmer works perfectly, and so do the flashers, although I'd never use them. These were very easy to install. If you try this, I have an F224, and used all of a 50 foot roll of wire. Those with good eyes will see I also installed the Polk speakers everyone thinks so highly of. I think they are an excellent upgrade, and will probably add an amp later.
