Could you just replace the factory bulbs with  a led bulb in the factory  socket just wanting to improve . from the dim yellow lights and not wanting to spend  $300.I am not that desperate. I have aimed the factory rear lights and they do a pretty good job just a little dark  right in front of the tractor for about 30ft. Has anybody tired it?

I need to add I am not talking about the fender lights  they are fine. I wonder about the light strip in the  front of the hood now its like a dim flashlight  really do not do anything.

I looked into those Rectangular lights, for a 4440 conversion and found 2 different "wattage ratings" ; but I never went that direction (bought a light bar instead, for that tractor).

I see Larsen lights, has those lights at 20 watts each(55 and 60 series) , and it looks like you would need 3 or 4 total. (EDIT: I see there is a special instruction about 50 series, mentioned on the Larsen lights site = Can be used on the 50 series too, but a new front holder for the lights is needed. JD part numbers :)

I, also, see Tiger Lights sells some LEDs, for that tractor front hood, at 30 watts, but just barely higher lumens, that Larsen lights. (seems odd, to me such little different, but 10 more watts advertised)

Hopefully, someone has installed EACH product and can help you, on a review.

2nd edit: here's a link to Larsen Lights conversion for 50 series ($249) LED-3000 {obviously, their must be a difference in those older 50 series nose cone parts}

This must be the kit, from Tiger lights ($380) for a 50 series conversion:

If you are not picky about keeping it looking factory done, this has served me well for two years on my 4450. Bought the light bar for less than the light kits.
