Yes, definitely switch to the LED's, and while we're at it, get the cables and power supply updated, for all units that are pre-2002 for sure.
As for the LED's, there are a few amps out there which have apparently some problems with premature burn-outs. Since we learned of the so-so quality with the LED's, we changed the marque and also switched to a more "secure" voltage.
