Approximate average CP upgrade in performance
[Stock reflector bucket]
1 Brake filament from 2057 to #3496 is 30%
2 Parking filament from 2057 to #3496 is 50%
[Modified reflector bucket]
1 Brake filament using #3496 is 'additional' 34% with most improvement in center lamp bucket output.
2 Park filament using #3496 is 'additional' 20% with most improvements in center lamp bucket output.
3 Smallest increase was on outside lens bucket(s) due to smaller physical size reflector.
So, in short, you get more candlepower output for close to the same wattage used on upgrading to #3496,
but when "combined" with reflector upgrade as well you get another 30% increase with much brighter
(+100%) backup lights and center bulb output. Rear lamps appear to display multi-faceted lens characteristics
as opposed to solid 'dull' lamp illumination. This look is considerably more eye appealing and distinct.
Backup light output displayed the most ofall with a whopping 100% improvement!
You can now get the "halogen" hi-power bulb look without the problems of wiring harness, brake switch,
turn signal switch ratings and overheating sockets. Now, it will take some patience and a few hours to do the
whole job. One of the interesting "side effects" is the viably appealing "jeweled" effect provided by the
internal red lens itself. This is near invisible using the stock reflectors but when enhanced to focus the bulbs
better the refraction through the red lens now looks like it has facets or a jeweled effect!
