Having worked in the aircraft manufacturing industry at the sharp end of developing designs and integrating them into aircraft, these lamps are most likely specified for a specific installation. Until one knows the rest of the helicopter design, you cannot say these are like for like. eg. What is the expected heat dissipation rate? What heat is the reflector taking away from these lamps as part of the design? What shape is the reflector (affects filament position in the bulb)? How many running hours is expected? The fact that they are similar "car" lamps bears no parallel and shouldn't be assumed.

I'll just leave this thought here...... this is a VW which I was asked to repair 4 years ago. It had direct connection high power lamps rather than the load passed through a relief relay circuit from the battery. The problem didn't manifest itself straight away. The guy was lucky in the end that he didn't have a dash board fire which couldn't be easily accessed. The only way of stopping this particular incident was disconnecting the battery. The circuit had eventually end up being "un-fused" through a multiple failure that changed the circuit current flow paths because the switch had melted and changed shape inside.

This was the state of the front lights loom with the wire melted into several other wires next to it. Fortunately in this case the loom was short in length and only went from the fuse-relay panel to the headlight switch. All inside the dash area, so extraction for repair was fairly easy.

By all means increase the lamp whiteness/brightness with car lamps from Osram, Philips, Razo's etc., but not at the expense of drawing extra current (ie. above 55watts) and roughly doubling the amps drawn.

And............ this guy hasn't returned to his posting to tell us what lamps he fitted that caused the reflectors to melt in his Scirocco.

I hear no relay "clicks" when the my Scirocco's lights are switched on, so I can only conclude until I see a circuit diagram, that the lamp switch is taking the full whack of what may be switched on. Contacts inside these switches are not big, are quite delicate and designed for what is normally expected plus a little. A failure is not necessarily a burn out as above illustrates. Once the switch fails, who knows what it will "reconnect" into the circuit which you may have no control over.

Surposdly they do. I doubt they actually do though.
