The only slight hitch was two small tabs at the base that are only designed to prevent you from putting the H4 into the HS1 socket. They are very easy to flatten with pliers, I saw a picture on the internet, but I can't find it now.<br /><br />So I divided 21,000 km (almost all on low beam) by 70 kph average = 300 hours. Next time I will suggest that Mary Ann use the high beams a bit more to stretch the life of the bulbs.Lost Motorcyclisthttps://www.blogger.com/profile/08873504561959138792noreply@blogger.comtag:blogger.com,1999:blog-2156536327610779049.post-36613079900892597132010-05-28T09:45:23.429-04:002010-05-28T09:45:23.429-04:00Reviewing my comment ... one thing I should note. ...Reviewing my comment ... one thing I should note.

Hence the notation PX 43T compared to P43T.</i>'<br /><br />The HS1 is now the 'standard' bulb for new two-wheeled vehicles in the United States, but sockets which support the HS1 bulb will also accept the older H4 bulb. (The thicker middle pin prevents the HS1 bulb from fitting into an automobile light socket ... but the reverse works fine).<br /><br />Approximate life expectancy of an HS1 bulb is in the order of about 300 hours. As the two bulbs in the scooter were most likely from the same batch from the same manufacturer, it's not that surprising that they burned out around the same time.<br /><br />H4 bulbs are available from the Tire for $4.35 (part 20-9107-6) and for <a href="http://cgi.ebay.ca/2x-H4-HID-Halogen-Car-Bulb-Lamp-12V-100-90W_W0QQitemZ320538708363QQcmdZViewItemQQptZMotors_Car_Truck_Parts_Accessories?hash=item4aa198898b" rel="nofollow">significantly less</a> from the Far East over eBay ;-)Madeyehttps://www.blogger.com/profile/02593933575568389288noreply@blogger.com
