Day Time Running Lights (DRL's) made easy... Part 2

That's a neat solution.
There is an engine running signal at the CCU, which will allow DRLs to only operate while the engine is running. There's another engine running signal at the front bumper of the TD4 FL1.
Proper DRLs are only supposed to illuminate once the vehicle has started moving forward, normally extinguishing when the handbrake is applied. However this is quite difficult to achieve on the FL1, without some monitoring of the PWM speed signal.

Is road speed one of the items of data in the ODBII diags?
Would need some micro-electronics like an Arduino to talk to it to determine if the car is moving but probably the easiest option if speed can be read through ODB.
What the ODB diags won't say though is whether the indicators are on. Didn't you say a while back that the DRLs have to extinguish if the indicators are flashing?
The speed signal comes from the ABS ECU on post A1 chassis number vehicles. I'm not sure about the earlier pre-A1 Freelander, as the earlier system was pretty much replaced after the 2001 update.
The speed signal is used for the speedometer, and for the variable volume control on the FL1 stereo, after the facelift FL1 came out.

Only if the DRL is in the same light lens as the indicator, or is within a certain distance between the two lights.

I had a go of making my own DRL version with two large hand torches. But got sick of bending down to switch on and off and then replacing the D type batteries were becoming to expensive.
Plus when it rained the botch tape never really kept the torches in place as I would have to stop to pick them up when they fell off.

It did have compensations in wondering when the big Golf balls on windy days would fall off and roll into the north sea. Twice happened not when I was there 1988-89 Or the howling winds hitting you when on guard duty on the hill while viewing Hermaness at day or Sullom Voe at night. Not forgetting the howling wind when trying to get of Shetlands. Northern Lights Up Helly Aa Simmer Dim 24hr sunlight RAFT Racing or 24hr stinking drunk getting a sun burnt bum.
Guard Duty with live ammunition against Irish terrorists possible attack our recently white picket fences. I could go on but this will be book form or a tome with cartoons.

Sadly signing the official Secrets Act I can only give the Soviet version. Mine was (Man on shift a lot nothing to see here). Proud of that one
. Quite enjoyed being on shift in the NLS especially when the repaired the Nimrod in the Hanger behind me. When quiet nights was abound the lads on night mainly show me around the aircraft. I used to set out the Detachment tool boxes and spares when the crews flew out. Chuffed of at least doing my bit.When I started at Kinloss and stuck on guard duty on the other side of the airfield NMSU next Findhorn. Half dozing in a porta loo guard post with my feet cooking on the bar heater. A sudden Rooooooooooooooaaaaaaaar disturbed my sleep lets just my bowels were not ready. There in front on the runway was the awesome sight of the Lightning taking off. I was young I was nervous I know I know what an EXPERIENCE. Tom Cruise would have run a mile. I felt sorry for the Ground Crew having to light the blue touch paper and legging it. That must hurt some pilots taking off. But I digress. When I went to Lossies due to Kinloss being repaired in 87 my hanger had a beautiful Jaguar siting in there. Even being that close you can admire the craft as a work of art. Anyway welcome to the rambling of a old RAFITE 1981 to 1990 Stafford Belize Kinloss (Falklands) Saxavord Buchan (Falklands). There a few of us old guys still knocking around on here during the eighties, to give these young pups a run for there money.
This is where DRLs need to be positioned, to be legal for MOT purposes.
According to the .gov website, DRLs come on when the engine is started, here's the quote.
"DRLs activate automatically when the engine is started and remain on unless the headlamps are switched on. They may however remain off in some low speed and stationary situations. In general all other lights should remain off when the DRL are on but for a limited period some vehicles may be available which automatically activate the rear position lamps at the same time as the DRL.
DRL may be combined with other lamps. For example some manufacturers use the same lamp for both the DRL and position lamp. In these cases the DRL automatically dims to function as a lower intensity position lamp when the headlamps are turned on. DRL placed close to direction indicators may also automatically dim when the direction indicator is active. This is to ensure that the direction indicator is not masked by the light from the DRL".
Hope this helps.

In that case would they be classed as modification or the same as adding a pair of spotlights. On my late 2002 I never had any DRL fitted.
