Can you plug and play Halogen to LED headlights?

Yes. Morimoto XB headlights.

Although, if they are anything like the XB headlights for the 3rd gen Tacoma reviewed here: https://www.tacomaworld.com/threads...ector-headlights.589465/page-66#post-21000702

The results are about equal with a $7 H9 halogen bulb for the low beam, and underwhelming for the high beam (dimmer than stock). This may have to do more with the fact that they use a third projector for the high beam, instead of a reflector like stock.

Still a decent upgrade over stock and MILES better than any drop-in LED bulb, but you'll have to decide if the cost is worth it.

 

Thanks Tory. The price difference between those and a bulb replacement is somewhat staggering!

 

What is involved to make the H9 bulb fit? Searching for the thread but so.e many to read thru.

 

I have the last version of xenon depot the ones before the pros ones for my lows, highs and fog lights. They did fit without cutting the dust cap. Overall they are brighter than stock for sure. If you want max output than probably go another route. The output on the fog lights are very impressive.
