I have seen other posts on strobe lights being installed on the Goldwing, and some reference hyperlites. However, I haven't seen a post on how they were installed on the Goldwing. My Goldwing is a 2012 Level 1 model. Here are the steps I took to do the install, followed by pictures of the install.
1. Determine where you want to put the hyperlites. The brake lights come as a pair, and stick on the Goldwing with adhesive tape. You can also buy a bracket that goes on the license plate and it puts the lights on either side of the license plate. I have a bracket, but decided to install the lights just under the trunk; one light on each side of the trunk/saddlebag levers. In this position, the hyperlite wiring needs to be connected to brake wires inside the lower panel of the trunk.
2. Remove the left lower trunk tupperware. The left side lower panel comes off by removing the screws on the inside of the trunk. Then, gently pull the top of the cover back to disengage the grommets and slide the whole panel to the rear of the bike. Remove the right lower side panel. Removes in the same way. Remove the center lower trunk tupperware. Four screws hold this piece in. Once the screws are out, the lower panel slips to the back and off.
3. Find the location of the brake wiring to tie into. For me, I opened the outer covering of the wires toward the right side of the trunk. You need to know which wire is the ground (green), normal switched power (Brown/White), and brake light power (green/red). The hyperlites install with Posi-tap connectors, so no stripping of insulation, splicing, or soldering is necessary.
4. Install the hyperlite modulator. The modulator is a small rectangular component with five wires . The three wires that connect to the motorcycle as follows: (1) Modulator red to the brake light power (green/red); (2) Modulator gray to switched power (brown/white); and (3) Modulator black to ground (green). Note that there is a green wire that is looped on the modulator. Left alone, the modulator will continually flash the hyperlites. If you cut the wire, the hyperlites will flash for 5 seconds and then go solid red. I chose the second option. Note the picture showing the posh-tap connectors.
5. Attach hyperlites to bottom of center trunk panel. I placed the lights on the bottom of the trunk panel. If you choose a different location, you will need to route your wiring differently, but the connection is the same.
6. Route wiring from hyperlites through the center panel and connect to modulator with posi-tap connectors: All blue wires together and all brown wires together. I did not shorten the wiring because if you need to remove that center panel in the future, you need to allow slack to reach the connectors to disconnect. In the future, I will put quick disconnect plugs in to make it easy to remove.
7. Dress up the wiring and reinstall the trunk panels. I used zip ties to help hold wires in place.
