Hi All
Added some indicator bulb DRL/indicator LED bulbs today to my S-type R, For under £20
theres no ready to go kits for the PY21W bulbs our cars have, so i made a set.
And i must admit they look great
got the bulbs off ebay for under a £10 from Hong Kong, Came in under a week, they were so cheap i bought a extra couple of sets as spares
I had to alter them completely, the led bulbs were a rubber grommet push in type, which i thought were poor.
So what i did is mount the led bulbs in two spare indicator bulb holders, rubbers removed from new led's, lampholders drilled out, new led's glued into jaguar holder with PU adhesive, so they push in proper, and i used a old bulb base so it plugged straight into the old bulb holder, I don't like cutting and chopping the original wiring, this is fully reverseable and the old style bulbs can be plugged straight back in, No jaguar wiring or harnesses were damaged or injured in the process of this conversion, lol.
One thing to remember on these, the lamp holders are wired different, the case of the bulb is positive and the centre is negative switched
I tapped all the wiring in manufacturer style black cloth tape, for the OE look
I also had to add a relay because jaguar use a permanent feed to the bulb and they switch the negative/earth to operate the bulb, so the relay converts the negative switch to positive switch
The set came with resistors, but they are not needed as there controlled by a ecu and the resistance of the relay is enough for the ecu to recognise the bulb is healthy
I got the jaguar indicator bulb holders and relays, there was only one s-type so 2x lamp holders and i got over a dozen relays, same as the smaller ones in the fuse box, for a Fiver, at my local scrappy, Mc Guinesses.
I fed the DRL out of the fuse box in the engine bay, I can also turn them off there if i don't want them on all the time, mine come straight on as soon as the engine starts
here are some pics
