I use H4/9003 bulbs for headlights. They are extremely bright. I had them in my 1025R and now in the 2032R. The ones I got aren't available anymore, but these are similar:

The rubber seals on the back of the original bulbs won't fit with these, but that doesn't see to be an issue. I pressure wash my tractor and have left it out in the rain without problems. These bulbs whine when you turn them on, as there is a little cooling fan in the housing (at least mine do, not sure about the ones I linked).

I found a link to these exact BEAMTECH H4/9003 bulbs somewhere either here or on Facebook a while back, & I installed them on my new 2018 1025R a couple of weekends ago. I bought the optional Deere LED work light package & the factory halogen headlights seemed pretty weak & an ugly yellow light in comparison. I haven't used them much, but in my limited usage so far they seem to have made a nice difference. I haven't noticed a whine from a fan or anything, but I suppose it might be there. I assumed they just have the fins in the rear to dissipate the heat.

I was bummed originally when I discovered that I wouldn't be able to use the rubber seal boots (it also looked like it would be a pain to get the hold down wires in place due to the extra bulk sticking out the back of the bulb) until I found a thread here where someone else installed these. On this particular brand & type of bulb if you twist & then pull, the flange that gets captured under the wire in the headlight housing will come off of the bulb shaft. The rubber seal boots can be used if you cut out the small center part that has the holes for the prongs to fit around the bulb shaft.

I trimmed out the center of the rubber seal by trial & error until I could just barely get the bulb to push through & twist lock into the flange with the seal behind it at my work bench. Then I took off the flange, put it in the headlight housing & fastened it in with the wire hold down. I then put the rubber seal boot over the back of the headlight housing & installed the new bulb by pushing it through the hole in the seal & twisting it until it locked in the collar. Then I just had to plug it in & I was good to go. The way I did it the rubber boot seems to have a really good seal & I don't think I'll need to worry about water or dust & dirt getting in.

As an FYI to anyone considering upgrading the headlight bulbs to LED, the latest parts catalog for the 1025R, PC13294, lists part number AXE16948 as the bulb for the head lights & the two fender work lights. This is the 862 type bulb that folks are swapping out with the JDM ASTAR 881 type bulbs from Amazon. I don't know when the change to H4 type bulbs in the headlights was made & if it was a permanent change, but the current Deere parts catalog doesn't list them. My new 2018 1025R FILB has the H4 type bulbs. I would suggest taking a look to see if you have the 862 type or H4 type headlight bulbs before spending money on anything.
