Some switches are adjusted by placing a small gauge drill bit, usually marked numerically not necessarily fractions, such as a #43 drill bit size for example, in the B/U switches adjusting hole. You generally place the shift lever in Park or Neutral, place the drill bit in the adjusting hole until it sets a predetermined depth, once the drill bit has seated properly, secure the B/U light switch. Some B/U switches on the columns are loosely mounted and slide to adjust, you place the shift lever in park or neutral, shift to reverse, check B/U lights, and if ok secure the switch.
