Most of the rechargeable lighs that plug into the cigarette lighter actually won’t RUN off the cigarette lighter, they’ll only recharge. The charger module will usually only supply about a 500 milli-amp current to the batteries, optimal for charging them but not enough to run the lights.
I have two of the lights that Dtro showed above hard-mounted for running on the front of my boat, but I took out the batteries an wired it to my 12 volt battery in the boat. So that’s an option if you want the candlepower and lumens that a handheld HID light rechargable has, but you don’t want the heft of a battery-powered rechargeable…just take out that heavy battery and add a cord to run it directly off your 12 volt system, off a cigarette lighter, etc. They’re still big, yes…but they are at least lightweight behemouths at that point.
Since those HID lights are hard-mounted to my boat for running, I also keep a sub-$10 spotlight in the rear for things like casting, pointing at beaver and muskrats, lighting up areas when formulating anchoring plans, etc.
