Are you wanting to enhance your lighting only off-road or while on the road? All the light bars and other add on lights are generally illegal to use on the road. With good reason, as they are totally blinding to oncoming traffic. If you are off-road it doesn’t matter. On road you are pretty much limited to headlight replacement with better/brighter units. Look to something like a replacement headlight kit with led projectors. My understanding is a simple bulb swap is likely to make things worse. You really need the unit to be designed for an LED bulb.
Not all of us are brainless window lickers. I am very aware of how bright these lights are, and will always dip my lights for oncoming traffic, most times before I see the oncoming vehicle. It's easy to see the haze from their lights on the other side of a hill or curve. I use them on-road in rural areas and have been able to brake for wildlife on many occasions to avoid hitting them. Interesting thing that I've noticed is because they completely illuminate the roadside, deer tend to freeze instead of run, which does help. I'm not sure of your locale, but local law enforcement has never stopped me, and a few LEO's (acquaintances and friends) have quizzed me about them, asking how effective they are.
YMMV...........
