If your rig has the small lenses like mine, I just swapped out the bulbs for brighter LED ones. You do not have to add any extra power or wiring, just swap the bulbs. Did this on our rig last year, and they are much brighter. Heck, now they are actually useful!
We added bulbs from this brand, but the actual bulb has been superseded, probably by another version claiming 8 million lumens or something. I think the lumen claims are wildly exaggerated but they will be much brighter than OEM.
