XC90 Rear LED Light Clusters
Hi All,
Inspired by the new breed of Volvo - especially the XC60 - I couldn't get the idea of banks of LED lights in the rear light clusters of the XC90. I'm sure I saw something on the XC90 forum not too long ago, and taking a look at my own car realised that the red lenses above the main side lights/indicators/reversing lights/brake light clusters are in fact just that, red lenses. There is nothing in there. This got me thinking, I could adapt these to have a bank of LEDs in. So I got hold of some LEDs (www.rapidonline.com are a great source of electrical components), and have wired them up. In each side there are 10 No. 8mm dia superbright red LEDs with clear lenses. These are wired up as two banks of 5 LEDs in parallel, to get the correct voltage across each LED. These are then just simply connected to the leads supplying the rear sidelights (black and white cables) with a couple of Scotchlok cable connectors. The LEDs now come on with the sidelights. In this configuration they are only drawing approx 0.5 amps each side, so should be okay with the cars wiring. If I'm honest I rushed this project somewhat (lots of report writing to complete for Uni before starting back next Monday!), and the LEDs are not spaced as well as they could be. Of course I know this because I built it, and am rather critical of my own handiwork at the best of times. But at night it's not that obvious unless you look very hard. So Mk2 is in the pipeline. This time it will be 18 No. 3mm superbright LEDs wired up in 3 banks of 6 LEDs in parallel each side (again should only be approx 0.5 amps each side). But this time I am going to take some time and mount the LEDs properly to some 5mm acrylic and using some self adhesive PCB track so I can solder the LEDs in properly. This should ensure that the LEDs are all accurately spaced. Also, because they are smaller they won't look as obvious as the current 8mm ones. Cost of components for the Mk2 version should be somewhere in the order of around £24 including all connectors, PCB track, LEDs, acrylic, fly-leads etc. The pics were taken this morning before it got too sunny. Even in bright sunlight you can see there are LEDs there when you are behind the vehicle. At night or in bad weather conditions they will look awesome!

Looking forward to seeing that, I have been thinking about having it done but was not sure how to go about it.
Will be on the look out for MK2 and how it was done.

I looked at this a while ago whilst putting on the trailer electrics, how though do you remove said "lenses" removing the light clusters was easy but the lenses above the light clusters? - I didnt spend long looking though.

Was thinking of doing something like this myself. A quick Question, are your leds as birght as or duller than the brake lights?

Hi Guys,
Just checked out ebay. Sure looks like a nice easy ready made solution to the LED requirement. The length of the available space to put the LEDs in the top sections of tail light are 345mm, so the 24cm length ones the closest? Not sure if you could buy the 48cm ones and cut them down? Would depend on how they are wired up (would need to check load/voltage/current/completion of circuit etc if cutting). The first set I have done I simply drilled a series of 8mm holes where I wanted the LEDs, then simply glued the (8mm) LEDs into the holes. For MK2 I plan to cut out the rectangular section running down the centre back of the lens, approx 15mm wide, with a saw attachment on a Dremmel drill. Then the 18 x LEDs per side that I have attached to strips of 3mm acrylic can be bonded in place to seal the unit again. Uni has taken over at the mo, so may be some time before I get around to fitting Mk2. Interested to see any other 'conversions on a budget', possibly with the LEDs off ebay? Chris. |

Have now found 48 led strips on Ebay at very reasonable price which can be cut to length have fitted to rear upper lenses by cutting hole in bottom and sliding strip up from bottom then working out length required and cutting sealed hole with silicone after first putting a piece of foam in will put photo on once it is dark to get full effect.Need to make sure that led's are facing right way towards out side.

any chance of photos of the inside of the light unit to get a better idea of where to cut etc cheers Ricco
