Screen shots below from a sales video for 2018 MHC 305RL.
LED light strips are visible on the cap in the first pic.
The second pic shows the control panel. One of the switches in the highlighted area will control the nose cap lights. Operate one switch at a time and walk around noting which lights turn on. If the fuses are all good - then there is a wiring short somewhere.
