Hi,

I wish to install DRL's (daytime running lights) on my 1995 XJR. I have found a spot where they will fit perfectly, but I am trying to figure out how to wire them correctly. Are there any ideas to help me? I guess I will be needing the following wires:

- ground (easy one)
- 12v that is live as soon as ignition comes on
- wire that dims DRL's as soon as headlight comes on (dipped beam)

All idea's are highly appreciated.

 

Since DRLs are usually not terribly bright or directional, could you not skip the third requirement:


.... or is it a legal requirement in The Netherlands?

I often turn my 'parking lights' on as DRLs, which includes the 'city light' in the headlights which I replaced with a relatively bright LEDs. But I'd like to have some automatic DRLs as well. My XJR being the dark 'Titanium' color really isn't very visible against a road or gray sky.

Will be curious to see how/where you wire them in.

Are DRLs on the X300 standard in some other markets?

.

 

How well do the LEDs show up during the day?

 

yep, Canadian spec cars all have them

Ah, that might indicate that wiring is present to easily retrofit then.

Which lights are lit as DRLs in Canada?


As far as the LEDs, they aren't terribly visible in bright daylight (although you can see them if you try), are moderately so in more overcast, and are great as "city lights".

Real DRLs would work better.

 

Al, the headlights for sure and I *think* the rear ones in the bumper (on an XJ40) but I'll check tomprrow - not paid much attention other than to the headlights - btw, any car brought into Canada from the States has to get DRL's fitted before it can be registered...

Strange ...my desire is to disconnect the rear running lights from the DRLs on my Canadian 97 VDP....turns out that the system is controlled by the Body Processor Module and maybe could be reprogrammed by a dealer

I'm very nervous about meddling with the wiring .....

 

Yeah, some things I'm willing to put a lot of time into, and others, well..... this one falls in the latter for me I think. But again it would be neat to easily enable.

So I wouldn't want to go to all the trouble of cutting into harnesses or reprogramming BCMs etc.

But if it is plug/play, such as just hooking into existing harnesses/plugs or swapping something like a BCM from Canada (with no other ill effects), that would be interesting to try.

.

 

Al, just checked the car, DRL's include all front lights/side markers (not the fogs) and the tail lights. The rear bumper fogs are not lit either, my mistake.

Larry

 

Hrm, that is interesting, sounds like a relay and/or control module overrides the headlight switch and just turns on the headlight and running lights.

 

So I wonder if a particular module (lighting?) from a Canadian car could be swapped into a USA spec car and one would have DRLs?

.

 

Seems to me that would do it, Al!

good luck

Larry

 

Yeah, might be a good experiment.

Anyone have any concerns that just plugging in a Canada spec lighting controller into a USA spec car would cause any issues?

..and I think/thought the controller in the trunk doesn't control the headlights? Not sure.



.

 

So doing some additional research, it appears the headlight controller for the USA and Canadian X300 is the same LNA2240BA part number, so I don't think that is what enables daytime running lights.

But I ran across the following thread at the JCNA forum that is interesting. It refers to enabling DRL on an XJS, but makes me wonder if it is a similar solution for the XJ.

JCNA Forums - Jaguar Clubs of North America


Anyone know if this may be a similar solution for enabling DRLs on a USA spec car?

I am a fan of DRLs, esp with my dark gray (Titanium) colored car, and am very interested in enabling them as the factory intended.

.

 

Don't mean to continually "bump" a thread, but am still wondering if anyone has any thoughts on my last post/question?

.

 

Hmm, my 1995 XJR is and always was a Canadian car. I do not have any DRLs on my car, or at least none that work. Last I heard I thought it was law in or around 1992 era.

 

Well, now that's interesting news

Anyone else can confirm if their X300 did or did not have DRLs in Canada?

.

 

Well I guess yours are fried.

here's what Transport Canada says (2014)

Canada's Motor Vehicle Safety Act (MVSA) and its Motor Vehicle Safety Regulations (MVSRs) require that all new vehicles sold in (or imported into) Canada and built after December 1, 1989, be fitted with daytime running lights (DRLs) that go on when you start the vehicle.
Vehicles built after December 1, 1989, that operate without DRLs are either:

• United States licensed whose drivers are visiting Canada
• have a broken or disconnected DRL function; or
• were imported when they were more than 15 years old, (the federal government does not have jurisdiction over these)

Provincial/territorial governments have complete authority over the road system and its use, including the licensing, operation and maintenance of vehicles.
With a few exceptions, the Government of Nova Scotia requires the use of DRLs or low-beam headlamps during the daytime hours. This law applies to all road users, including visitors.
Nova Scotia is the first Canadian province to pass such a law. Transport Canada is encouraging other provinces to follow Nova Scotia’s example.

 

..or disabled, bypassed, removed

So maybe it is possible lol.

 

Well, still interested then to see what enabled DRLs on Canadian cars.
