I promised (over amonth ago) I would post the neat flush mount John Deere 650 HT dozer worklight part numbers that I had our mechanic install in the rear bumper. You need two of each - bulb - #AT220508 @ $13. 27; eyeplate - #t175866 @ $10. 03; and o-ring - # t177080 @ $2. 55. Be sure your bulbs come with the disco ball looking reflectors they are available both ways. Sorry for the delay we just got our monthly bill from the John Deere dealer. Be sure you go to an industrial equipment dealer not an agricultural dealer.
