Well, I'll have to sort of disagree because I think it all depends on which lights your talking about. I have the Caddy (Rocket) lights and replaced the regular bulbs with super white LED bulbs and it made a heck of a difference to the better. I bought the Super White for the amber lenses and the SR (Super Red) for the running/stop lenses. In a dark garage I put the LED's in on one side and regular bulbs on the other and there was a big difference when they (LED) were lit up. Click on "Auto Indulgence" to see the ones I used. You can also get them at Auto Zone.
