9005/HB3 bulbs can be replaced with HIR 9011 bulbs. 9006/HB4 blubs can be replaced with HIR 9012 bulbs. "HIR" stands for "Halogen Infrared". Google and find threads that discuss HIR technology. The bases of HIR bulbs have to be trimmed to allow them to be used in place of 9005 and 9006 bulbs -- see the attached instructions. HIR 9012 bulbs are used on John Deere 9000 series equipment such as combines. The John Deere part number for HIR 9012 bulbs is AH211917. I too replaced the 9005-6 with 9011-12 bulbs on a 99RX300 about eighteen months ago. Results are great. Much more light ouptut with the same consumption of energy. Excellent choice. You should search for the bulbs (Google), since the JDeere ones are not the least expensive. When replacing the bulb types, you will need to partly cut out the flanges of the new bulbs because they are too wide. It is easy to do (or to file down) since you have the original bulbs to 'copy'. Over here driveing at night is a nightmare..i ran over 4 cats and hit 2 dogs in a 1 month period of driveing at night SAD!!...completely different roads compared to north america...i really appriciate your help guys!!thanks

The high beams are one kind of bulb, the low beams another kind of bulb. The two also do not 'aim' independently: the lamp housing is 'aimed' as an unit (screws inside engine room, on top of housing - screw 'in - clockwise facing the screw' to lift aim). The dealer must know the correct bulbs to install. I have replaced those bulbs (which are not very bright) with 9011s and 9012s, which cost more but have many good characteristics, incl. more brightness and long life, with same wattage. Normally. because of the shape of the connector and the shape of the flanges on the bulbs, you cannot install the wrong bulb in the highs or low beams. Maybe something is wrong with your power supply to the bulbs? So you replaced the high beams original 9005 to 9012s? and it fits perfectly ? can i ask what make brand did you get these? thanks
