Only use 35 watt H4 bulbs or bad things happen
« on: July 12, 2019, 12:52:47 AM »
I fried the ECU, stator, and dashboard in my CC 300i by using 55 watt H4 bulbs.  A word to the wise.... stick with 35 watt.  The LED equivalents when I had to replace the bulbs originally were to big to fit, and I had some 55 watt H4s, so I installed them and loved them... so much brighter... but after two years of use, $400 in parts plus labor.  (I found a used dashboard from a seller in Italy, otherwise the parts total would have been $700).

Now there are some companies who can make any parts of our vehicle on custom order, yes they charge bit high but they provide our desired product, I have Ram truck which i am using for Blocked Driveway Towing Brooklyn, i changed its dashboard completely on a custom order.

I live in the desert.  Riding Citycom since 2009.  Lights not flame throwers even on high.  Would have loved a little more light.
Chose to stick with the 35W not just for the draw on the electrics, but the potential to  melt housings in 115 degree desert heat.   
I love the two 35's are on full time for light and security when one burns out. 
Has happened 3 times in 17000 miles.  Annoying to replace and not really any shortcuts I have found that work.  I have gotten pretty good at pulling the front plastic.  Just commit to doing it.  Last time I did it I could not believe how easy it was.
Good idea to always replace them both when one goes out.
So many things I love about the Citycom.  Another one is dual tailights.  Again, safety factor if one burns out.  I see big bikes with one dinky bulb.  My new Citycom has LED in the back so maybe I will never have to replace.
Hope I have not breached any etiquette by replying to an older post.  Not much action on the site.  This is the only one I ever post to.

Hi,

Why do the bulbs blow - is it just too hot and dry there? Dirt/Sand on the bulbs's glass concentrating heat?

I changed to 10W LEDs so I haven't had any problems. But the change wasn't straightforward because there is a "headlight control unit" that requires a significant current drain to turn on, and 10W was not enough, so I had to replace the HCU with regular automotive relays. So if you do decide to get LEDs, get some high wattage ones, making sure they'll fit as the OP noted!
