My CMax seems to blow both headlamp bulbs and tail lamp bulbs more often than I think should be normal service. Is there a Voltage Regulator on the CMax and could this be an issue? What should the normal DC Voltage be when the gas engine is running vs the elect engine running?

FYI I'm currently using Phillips H11 headlamp bulbs and stock tail lamp bulbs. I have previously tried Sylvania Silverstar bulbs too. The Sylvania bulbs didn't last, and both bulbs went out at the same time. The dealer told me that I should only use the standard bulbs.

That does sound excessive.  Our 2013 has all original bulbs except for one tail light.

I believe the voltage should be about 14-15 VDC when charging.

How many miles on the car?

Something does seem amiss.  I've yet to have a bulb go out in 5 years of ownership.

 

There is a DC/DC converter module that regulates the charging of the 12V battery and supplies power for the 12V system.  There is no alternator like a conventional car.  The highest voltage I've seen from monitoring the voltage at the converter was 14.8 V when the State Of Charge of the 12V battery was very low.  Typically, the charging voltage runs about 14.4 - 14.6V until the SOC gets very high.

 

You may want to monitor the 12V battery voltage while driving by one of the following ways:

1) on your smartphone via ForScan (about $30 for ELM327 OBDII adapter and ForSCan App) see forscan.org

2) on the Engineering Test Mode display available on the left hand dash display 

3) on a volt meter that plugs into the cigarette lighter.

These halogen bulbs should never be touched by ones fingers - my apologies if you are aware of this already.

I agree with Plus 3 Golfer.  Highest voltage I've seen is 14.8 (based on the cheapest cigar-lighter-LCD-voltage-tester I could find on Amazon).  I've yet to have a bulb burn out.

I haven't lost any bulbs yet at 175k mi./ over 5yrs. Was 15 volts today with 12.4 volts before starting, stabilized at 14.9 volts. :)
