Philips Automotive Lighting 12831WLEDX1 DRL9 LED Daytime Running Lights

excellent set of daylight driving lights! This is a very easy kit to fit, it took me about 30 mins . The instructions are very clear. All I would add is to plan the install don't do it as you go. Take 5 or 10 mins and look at the best place to mount lights and the best route to run your cables. The instruction have diagrams of where lights should be fixed and the cables have plugs which plug into the control unit all it leaves you to connect is the power leads to the battery. These lights are very bright and a great safety feature! I have had these lights for a few months now and still loving them. No Problems!

We have these fitted to my Subaru Forester.Note: some people are saying they go off after a few seconds, working intermittently. This only happens if your alternator runs at a lower voltage than standard when the battery is almost fully charged (common on Japanese cars like my Subaru). It’s simple to get round this problem by wiring the relevant wire into the ignition feed.These have been so good that we have just ordered a second set for my Toyota Alphard, happy days!5 stars.

This product is so good this is my second purchase. They are very well made with a metal case and 9 led lamps. They come with a seperate control box heat resistant wiring and plenty long enough to locate wherever you like. The wiring was easy to follow with me being an Electrician and should be for most DIY people. They work on a voltage principle with the voltage changing during the start/stop phases. They sense the voltage drop during start up and stop. They are also connected to the low beam lights and when switched on they switch off making them road legal. Do not be tempted to connect them direct to the battery and always use the control box. As direct connection will cause them to fail and blow the led driver.

A very well designed and manufactured product that works extremely well, sadly I would have and indeed do give the product a 5 star rating, however; the reason for my 4 star rating was that the installation instructions were unclear, very small and most of all the wiring instructions did not add up, even Philips Technical Department could not explain why there was an extra wire in the circuit, even they were baffled. Had it not been for my 50 years working as an electronics design engineer, I would have probably been in trouble. The good news is that for anyone buying these lights, if fitting them to a standard car, then simply earthing the blue wire was all that was required. The control system works by sensing the rise in battery voltage when the engine starts and the control box does not simply contain a couple of relays. Excellent design, even if a lot more costly to develop and produce, probably hence the price, but worth every penny.

Fantastic lights I’ve used them for day time driving lights & they look great

The good news...the product is very easy to install, the instructions are clear and when it works the lights are very bright.What I didn't rate was the need to wire one of the wires to the -ve using a 'lucar' type connector...an abomination but a minor matter !!However this product is wholly unreliable. In short I happened to be driving in front of the nissan navara upon which I had installed the lamps and noticed that they sometimes cut out altogether, flashed on and off or worked normally. I assumed it was the ghastly lucar connector which was only working part time. I had damaged one of the lights (my fault) so I ordered another set only to find it worked equally intermittently. I swopped the wiring harness, 'the brain/black box' all to no avail. In the end I put a meter on the input to the box and this showed no problem with the wiring loom supplied (I had removed the lucar connector and wired the wire permanently to the -ve) but the output worked only intermittently. It was the same with both 'black boxes'.In short there is a serious issue if both boxes exhibit exactly the same fault. As I live in France it is not economic to return the item(s) but I would strongly advise anyone not to buy this product despite the manufacturer being highly reputable.

I decided to spend a bit more to get a quality set which would work reliably and I'm not disappointed. All the connector plugs are waterproof and the instructions were easy to follow. They're fitted to a 2004 Renault campervan.

Worth paying for a kit rather than individual components. Generally easy to install - took about 1.5 hours (10 minutes for the wiring and brackets and the rest faffing around trying to find the correct wire to connect the orange lead to). The instructions are poor though as it is mainly diagrams and little explanation. For example, the blue lead needs to go to an earth but why have it seperate from the lead that goes to the negative battery terminal?Once installed they work well and so far have had no problems with them.
