In stock housings you won't get good beam cutoff.

Bulb won't have any effect on your beam pattern, especially in a stock reflector housing that's basically a diffused flood light beam. If you want an actual beam pattern/cutoff and significantly better visibility, cheapest option is ACA housings with LED or HID bulbs with a decent ballast. From there, there's the Knight Drive LED setup that's pretty popular, and options all the way up to Sharp Light Innovations on the high end. You're just not going to get a good headlight setup using stock housings.

LEDs in the stock housing will scatter like crazy, I highly recommend against it. Check out Sharp Light Innovations or KnightDriveTV. Both have good aftermarket options. They are going to cost more than just a set of LED bulbs though. If you are keeping the stock housing, your best bet will be a good set of HIR (not HID) bulbs. Good luck!

I also give HIR thumbs up. About twice the brightness and the beam is... well... at least it's no worse than it was before. You need to trim one tab on the new bulbs, if you look at the old bulb you can figure it out. I used these:

https://www.ebay.com/itm/175141755268

And full disclosure there may be a bit more glare because of the missing "black top"... nothing compared to running an LED in the stock headlight.

If you want the correct HIR bulbs with the black tip you can get them from https://www.danielsternlighting.com/

This is the only real "upgrade" for stock housings. Anything else will scatter light like crazy.

Led bulbs in old housings are like putting Air Jordons on an old man. He will look brighter but not jump any better.

As stated many times on many threads across numerous boards (including Motorcycle boards), putting HID bulbs in stock buckets designed for Halogen bulbs is useless. The scatter is worse than the lack of light from stock bulbs since the light is not directed where you need it.

The trick to stock lens is to get bulbs that index. There are bulbs made for stock housings. 360 bulbs for the fog lights. You need to match the correct bulb per application. Too few sellers explain this. One bulb does not work in all.

As to farther down the road the brighter high beams will get more coverage.

Note be careful you don’t blind others.

This is the key, most LED bulbs work great but in our cars if you can't rotate the LED relative to the twist lock housing then the LEDs will not face 3 and 9 o'clock like they should to help with the pattern. Mine are stuck at 2 and 8 position because the bulbs can't be adjusted and I didn't do my research first.

‘The greatest issue on LED is the lack of knowledge and the proliferation of cheap crappy bulbs on the market.

the design and engineering has vastly improved these bulbs but the crap ones dominate the market.

Having that 3 and 9 o’clock adjustments means everything.

Mine were fully adjustable and work great. Much better than factory.

Please work with a well known light company as these are not like other bulbs were they all use the same thing.
