But I was hoping to find a way to defeat the Honda system, and keep the alternator at 14.4V as God intended, so I won't have to waste gasoline on the headlights. --- End quote --- In general it is recommended to turn the headlights on during the day for safety. My guess is that Honda considers having the headlights on during driving as standard; just be thankful they force you to make participating in traffic safer. |

Here in the US the NHTSA concluded that DRL does not improve collision statistics appreciably and they actually banned full-power DRL at one point because of concerns that it would interfere with the discernability of the turn signals in certain lighting conditions. Having driven a lot on 2-lane rural highways before moving to the vast metropolis that I now live in, I have to disagree with the NHTSA position. Headlights are a big help, especially on grey overcast days on those two-lane roads. Anyway, here in the US headlights on is not standard and Honda considers the half-power DRL as normal operation. On cars that turn the headlights off automagically when you turn the car off, as all three of mine do, you can just leave the headlight switch on all the time. If you don't have that feature, you have to remember to turn them on and off all of the time, which is probably why the OP is annoyed. |

My memory is that Canadians don't have the problem, so maybe UK as well. --- End quote --- Those places have mandated DRL. Does your car have DRL activated? --- End quote --- In the UK the DRL regulations started for new type approvals in 2011, so most 2012 cars, like the Honda Jazz we have, don't have DRL. |

I drive with headlights on all the time, with the exception of very clear days with excellent levels of light. Since the UK is predominantly rainy, overcast, or foggy -- sometimes all three -- the headlight switch rarely moves from its 'on' position. |

Sounds like it should be a bit higher, 12.6V: https://www.civicforums.com/forums/181-8th-9th-generation-civic/369269-alternator-12-6-volts-unless-lights.html |
