The plastic melts due to a loose connection not a larger bulb. If the bulb was drawing that much amperage the fuse would blow first. I have 55000 miles on original headlight and bulb. I noticed last week while removing the outer faring to install an amp my headlight plug had begun to melt. Sure enough one of the female push-ons in the plug needed adjustment. Glad i caught it in time. I have had that faring off too many times to count so I place the blame on repeated plugging on-off. Something else to check whenever the faring is off.

Ive read of riders having the plastic connection (plug) melt when using some of the high output bulbs.
On my fatboy I tried a Sylvania Bulb that I got at a Auto Zone and it burned out in a couple thousand miles, I was told by the parts guy at the dealer it was because of vibration. Im getting ready to replace my bulbs in the Road Glide and Ive been looking at the Piaa bulbs they have models for motorcycles and vibration.

The high-heat adapter can't hurt, but I've used the 80/100w bulbs on both my '96 RK and '07 SG for years without any heat-related issues. OTOH two friends that ran the same bulb, one with a '98 Softail and the other with a BMW GS had problems and bought a high-heat connector from Auto Zone. It required some splicing/soldering of the new connector into the existing wiring, but it was a simple solution. It might be worth noting that I also run a modulator which pulses the high-beam at 20-100% 4X/sec., and that reduces the heat considerably in daylight when high-beams are used (100% of the time).

Truck-lite L.E.D. 7" Phase 6. Really bright, extremely noticable in daylight and uses way less amperage. Only downside, it's not cheap but well worth the money.

If the connection is loose you raise the resistace which pulls more amps....Just a little electrical lesson. The plug melting with hi-output bulbs is normally due to the hi heat within the headlight bucket. I've been dealing with this for years by simply drilling a small vent hole in the back of the housing to allow the heat to excape. I can buy a pair of H-4's from Auto Zone for less than my dealer cost for so called motorcycle H-4's. Theres something wrong with that thinking.
