I have used the forums a number of times since buying my '07 Cayman S 2 weeks ago (thanks to all member who contributed) and wanted to post up this article following a fairly quick installation of the Philips Running / Daytime lights (DRL) on my Cayman.
The lights in question are these - Designed for safety
I have tried to take pictures of the process, but this is my first time submitting an article so hope I get it right!
OK, firstly, a picture of the kit itself which comprises a control unit, 2 LED units and 2 mounting brackets.
1) expose the battery and connect the positive (red) and negative (black) terminals from the control unit and feed the wires (which are very flexible) under the rubber covering the lining of the bonnet and into the storage compartment where you can mount it.
2) cut away the strut in the front grill to allow space for the LED and bracket to fit. I found using a sharp stanley knife and heating the blade worked well as the plastic is pretty soft.
3) You'll see that the mounting brackets have the metal 'grippers' punched through leaving a small gap, which I found perfect for attaching to the car, instead of drill and trying to fit with screws (which is nearly impossible without removing the grill and hence the bumper).
4) The green arrows indicate where the mounting bracket clips into the gap between the grill and the rubber cowling which sits behind the grill, it's a very tight fit and holds the bracket perfectly.
5) Next job is to feed the LED cable through the inside of the front bumper and through to the top where the bonnet release is (the plastic trim comes away easily from the inside of the bonnet lining where the bonnet release is). I use a trick by feeding through (from the bottom where the LED mounting bracket has been attached) some garden wire (covered in plastic so not to damage any paint work). I fed the wire between the grill and the rubber cowling and up behind the bumper and reached from the top of the bumper down with a small piece of metal with a hook on the end to grab the cable and pull it through - this is a very fiddly job, so have some patience! I then wound the garden wire around the end of the LED light cable and pulled it carefully through.
6) I then ran the wire up the side of the inside of the bonnet (inside the black trim) and to the control unit in the storage space. Repeating on both sides.
7) The Philips lights have a clever 'click' in method for attached the LED light into the mounting bracket. Do this and then move the bracket into the desired location, ensuring it is still firmly attached.
8) Repeat on both sides and then start your engine! The control unit recognises when the engine of the car has started and the lights come on automatically, and switch off when you switch the engine off - really easy.
The picture looks OK of the finished product, but I can assure you in real life they look 10 times better, the LED lights are near identical to the DRL on the new 911 / R8 in terms of the quality of the LED light. I would also say being made by Philips the build quality of these units is top notch. FYI - This process took me about 2.5 hours to complete from start to finish.
