It is. I put LEDs in the tail lights, too. Mostly, I use the Lario for short trips, and over a period of time I'd notice the voltmeter going down. Putting on the brake lights would send the needle into the red. Now, it really makes no difference, and the needle stays centered. The LEDs just seem to take the load off the old wiring and connections, and I haven't had to put it on the charger since.
