Extra LED Tail Lights to the Rescue
« on: August 28, 2013, 06:23:36 pm »
Last night my G5 tail light bulb filament burned and the bike became invisible from the back, as in the first picture. Fortunately the EXTRA LED lights I had installed long time ago came to the rescue and made it quite visible from the back (second picture).

This morning I took out the burnt out bulb and read its number 1077 printed on the base. I had a bulb (7225) that looked just like 1077 as shown in third picture and tried to fit, but it would not. Later I realized that the two pins at the base of 7225 bulb were not quite at 180 degrees to each other (they were actually at 150 degrees), but the slots in the socket are at 180 degrees. 

Went to a few stores and could not find any bulb or package with 1077 on it !  Finally one guy at an auto shop spent some time did some search and gave me a package (7528) and asked me to try it.  When I looked INSIDE the package the bulb was stamped 1077  ;D !!  There I GOT it, fourth picture.

Why is 1077 bulb sold in the package for 7528 ?

The 1077 is a 12 volt 5/20 watt bulb for a U.S. spec.
The 7528 is a 12 volt 5/20 watt bulb for a European spec.

The Philips part number for both of them is 12499 so appearently they are the exact same bulb that meets two different specifications.

An 1157 has a base with the same physical dimension and is commonly substituted, but I believe charts show the 7528 is a slightly brighter bulb at the expense of shorter life.  Researched a little when looking at LED replacement bulbs.

My Bullet had an 1157 in it and I put an 1157 LED in it. Worked great. I need to get another one for the Goose. But, thankfully all the panel lights in the Goose came as LEDS. It's nice to be able to see the panel in all lighting conditions. And it's got a lot more lights than the Bullet.
