Daytime running lights for Durango

Can anybody tell me whether Chrysler's DRL module can be fitted on US-spec
Durango 99? And if yes, where can I order the module online?

Alternatively I could try one of generic DRL modules available, but that
would involve splicing and rewiring which I'd rather avoid...

TIA,
Peter

What's the reason for the DRL retrofit? Moving the vehicle to Canada? Or
you're staying in the US but have been confused into thinking DRLs make
you safer?

The wiring for the DRL module is not present on US models. The easiest and
least problematic way of adding DRLs is with the module from
www.webelectricproducts.com .

Thanks for posting this PETER.  I?d also like to add DRL to our 97
Town and Country because we came from a 98 Chevy Blazer and we were so
used to the lights being on already.  When it was dark it would go to
our normal headlights, not just driving lights.

Retrofitted full automatic light controls seldom work as well as factory
systems, which themselves are not particularly dependable. Is it really so
hard for you to turn on the lamps by yourself when it gets dark...?

Full automatic light controls are also not the same as Daytime Running
Lights, which in turn are not the same as "driving lights".

Well, guess I'm confused then because I believe DRLs _do_ make me (and
others) safer.

Another reason might be that I'm not in US, and this particular country
requires DRLs. ;)

OK, thanks for letting us know! Webelectric site states their kit uses turn
signals as DRLs, but I need low beam headlights (yet another requirement).
I'll dig around...

Cheers,

Chrysler in the country of interest might offer a retro fit kit. Give a call
or write a letter to Chrysler in the country of interest. Also give a call
or write to Webelectric.

Which particular country? Different countries have different DRL
requirements, and there are many, many different ways to implement each
type of DRL.

You're right. Regs state that DRLs must be white, and must not exceed 800
candles in total. Hence I suppose I could use either low beam or fog lights
as DRL, probably at reduced intensity.

Country is Latvia btw... European Union regs apply here.

OK, then, the Canadian module will not work, because it runs the high beam
headlamps (intensity between 3,000 and 7,000 candela -- MANY times the
EU/ECE R87 800cd maximum for daytime running lights.)

It is basically impossible to get the low beams or fog lamps down to 800cd
without causing the color to be orange and the bulbs to blacken and fail
quickly. Most countries that adhere to ECE R48 and require DRLs permit
full-intensity low beam headlamps as DRLs, but some of them do not, so
check Latvia's code. My information (as of 2/05) is that Latvia permits
full-intensity low beams as DRLs. It's not difficult to hardwire the
headlamps to come on with the ignition. Fog lamps are NOT legal as DRLs in
Latvia, at any intensity (as of 12/04).

You may have even bigger issues to deal with (US headlamps that do not
even come close to complying with ECE R112 for headlamp beams, rear lamps
that do not comply with ECE R6 requiring amber rear turn signals, front
position lamps that do not comply with ECE R7 requiring white and not
amber, etc.) ECE-compliant front and rear lighting equipment for the
Durango does exist in South America. VERY difficult to obtain if you're
not there!

You may well find that the easiest way to have DRLs is to put on a set of
the Hella add-on DRLs, which are homologated to ECE R87 and therefore
legal in all countries that adhere to ECE regulations.  They make two
different kinds. These:

Geez, you DO know your stuff! That's right, low beams are fine as DRLs. I
sorta wanted to run them at 75% or so in order to reduce wear&tear on lamps
& alternator.

In fact I didn't know foggies are not legal as DRL... you know more than I
do ;)

This is not really an issue since my Durango is pre-2001, and lamps do not
have to be Euro certified. US beams are OK here, they even have a separate
clause in inspection regs stating so. All I need to do is to convert front
markers from amber to white, and modify turn signals (complete on/off cycle
instead of varying intensity, and ambers in tail). Total expense of about
150$...

Now, for 2001 and newer lights are major PITA as you've pointed out... as
are EU certification requirements. Frankly I think this is total nonsense,
and regs are made up specifically to protect EU market. Generally Euro
certification adds up to ~4000$ making all imports more expensive.

Thanks! These look good, but I suspect will be ghastly expensive. Will check
around...

Thanks again, you've been major help!

Careful here -- if you reduce the lamps' operating voltage by 25%, you
will be increasing one kind of wear and tear (bulb blackening) while
reducing another (plain old life usage). Net gain is negligible.

That's fortunate for you from a logistical standpoint, but US beams are
ugly when you try to drive with them after dark.

> All I need to do is to convert front markers from amber to white

You can drill the headlamp or fog lamp reflector and install a grommet
with W5W or T4W "city light" bulb. The front fogs are useless as fog
lamps, so you could even just modify them to serve as your front position
lamps.

> and ambers in tail). Total expense of about 150$...

E-mail me offline if you want details on a slick and clean way of having
amber rear blinkers *and* reversing lamps in the present housing, without
having to add a new reversing lamp (though you may still have to add a
rear fog lamp, and perhaps side blinkers.)

There are valid safety reasons to require EU lighting devices. Most of
them are very much superior to US lighting devices.

Naw, they're very affordable. I have a set on my shelf waiting to install
on my '89 Dodge Ram.

Glad to help.

Hmmm... didn't know that. Guess I'll just have to go thru electric diagrams
and rewire low beam so it turns on with ignition.

Euro beams are definitely better. My other vehicle is US-spec Isuzu Trooper,
and I've replaced original bulbs with hi-intensity ones (same wattage). It's
OK now, but still Euros are better.

I was gonna drill corner of the turn signal (it's not used anyways!), and
install white bulb there.

I agree, and requirement to have Euro lighting patterns is fine, but why do
lamps have to be Euro certified? Headlight beam patterns are easily tested,
and you don't really need a special equipment to tell the color/location of
turn signal/marker/brake lights. Eurocracy at work... :-|

That works -- or you can use that location for the side blinker.

That's just it: They aren't so easy to test as you might think. That said,
there exist some US headlamp beam patterns that aren't Euro type approved
with an (E) mark, but which are functionally almost identical from a
seeing/glare perspective, and you're right, there'd be no technical reason
for barring these. But there might be a logistical one: You and I
understand the difference between the junk US beams on your Durango and
the "almost Euro" US beams on, say, a US-market Audi, but how do you make
the average vehicle inspector mechanic understand?

> and you don't really need a special equipment to tell the

True, but intensities and angles of illumination are different for
US/Euro.

I know that certain distant vehicles against certain backgrounds are far
more clearly visible (at least to me) if they have full-power or dimmed
headlights on (I'm not so sure about "parking lights"), so I expect that
I have a similar visibility advantage when I use DRLs. I special-ordered
the module that is standard on the Canadian 300Ms and plugged it into my
US-market one, a 10-minute job for which the dealer estimated 2 hours labor.
