 The Rear Brake Switch is installed in the rear brake hydraulic line from the master cylinder to the caliper, typically on the left side ahead of the caliper. It is a hydraulically activated switch, meaning that at a certain level of hydraulic pressure in the brake line, the switch closes to conduct power thru it to the rear brake light. (1986-2019 used the same rear brake switch, P/N 72023-51E. It's possible to also use a NAPA P/N ECH SL147.)((http://​xlforum.net/​forums/​showthread.php?​t=49330)) The Rear Brake Switch is installed in the rear brake hydraulic line from the master cylinder to the caliper, typically on the left side ahead of the caliper.

-Early model Sportsters (1990-older) used a sealed-beam,​ 5-3/4" headlamp. In 1991, they were supplied with a headlamp lens (bulb housing) which uses a replaceable bulb known as an H4 version. The supplied bulbs were rated at 55w for low beam and 60w for high beam. Modern bulb model 9003 is also physically equivalent. Various brands and types of H4 bulbs are available including new LED versions. ​Not all LED units are sized the same so some testing of the physical depth (both inside the lens and behind the lens) is necessary to proper fitting. It is important to obtain LED bulbs that are compatible with the headlight lens design - It is important in order to produce ​a reasonable ​light beam similar to the original motorcycle style projection.+Early model Sportsters (1990-older) used a sealed-beam,​ 5-3/4" headlamp.

Modern bulb model 9003 is also physically equivalent ​and may have the H4 designation as well. Various brands and types of bulbs are available ​in the H4/9003 base fitting ​including new LED versions. ​However, not all LED units are sized & positioned correctly for the H4/9003 lens, so some testing of the physical depth (both inside the lens and behind the lens) is necessary to proper fitting. It is important to obtain LED bulbs that are compatible with the headlight ​housing ​lens design - It is important in order to produce ​an appropriate ​light beam pattern ​similar to the original motorcycle style projection.
  
-The low beam usually throws a narrow light, a relatively ​short distance. The high beam is a broader beam and is redirected (by the reflector) to throw light farther down the roadway.+The low beam usually throws a more narrow light, a relatively ​shorter ​distance. The front-most element in the bulb has a small reflector built into the bulb to throw the produced light upwards against the lens reflector in order that the light will be projected downward onto the road surface. The high beam (produced by a second element closer to the connector that throws light in a 360° pattern) produces ​a broader beam and is redirected (by the entire ​reflector) to throw light farther ​and wider down the roadway.
  
-Typical (recent) wiring practice is to supply the low-beam power on a Yellow Wire and the high-beam power on a White Wire. These wires come from the Left Handlebar, Hi/Lo Headlight Switch. With the introduction of the BCM in 2014, the handlebar switches are digital and communicate their status to the BCM over the CANbus. The BCM uses BLUE/Yellow & BLUE/White Wires to supply power to the Lo & Hi headlight filaments.+Typical (recent) ​HD wiring practice is to supply the low-beam power on a Yellow Wire and the high-beam power on a White Wire.

-    * (Converting to LEDs) - Because of the way these bikes were wired, you can replace the single current/​heat-activated flasher with a new electronic flasher that is capable of properly flashing LEDs or Incandescent bulbs. However, the indicator light may need to be modified by grounding one side and feeding power from the right and left circuits thru diodes to the power side of the indicator.+    * (Converting to LEDs) - Because of the way these bikes were wired, you can replace the single current/​heat-activated flasher with a new electronic flasher that is capable of properly flashing LEDs or Incandescent bulbs.
