I have been busy this last couple of weekends getting a few jobs done before my car hits the mean streets of Lincoln again on the 1st of April. Not least of which was to modify the front position lights in the front bumper into dual purpose by including a repeat indicator. The reason being that trying to leave my work premises on an evening is a lottery because of the roads around work. I have recorded the work done if anyone wants to see how easy it is to do.:) Sorry for the wind noise on the video.

Come on Tony, hows it done?! Very good mod and one I'll definately do - probably my first as a safety enhancement!

Tony, hows it done?!
Hi Ash, I will get round to doing it mate, honest, but as usual at this time of year just before I go on holiday every one wants their car sorting out before I go. I sometimes I wonder if they think I won't be back !!=))

So, how it was done. Things you'll need are:
1. Sharp knife (if you're not allowed sharp things - stop right here!)
2. Cordless drill and 3.5mm drill bit.
3.Some cable to extend the wiring up to the front indicators.
4.Some heat shrink tube and a heat gun.
5.Soldering iron.
6.Test light.
7.Some Araldite or similar .
8.

First you will have to remove the light units from the front bumper. Then using a sharp knife run it along the glued joints around the light until it comes apart, a little patience pays here.

Now get your led strips and if they wont go in above or below the sidelight bulb you will have to cut them at the cutting point shown. Then drill two holes to allow the wires to pass out of the light and stick the strips into the light body.

Once you have the wires through, mix some Araldite or similar epoxy type and stick/seal the wires at the exit to prevent damp getting into the light. Now shorten one of each pair of wires and part the insulation on the long wire at the same length and solder the short wire to the long one finish by sliding a piece of heat shrink tube over the joint and shrink it tight with the heat gun. Now you'll need to extend the wiring up to the front indicator lamp area to be able to connect into the live side of the indicator bulb. I used a length of speaker cable as these are LED's they don't need much current, also the speaker cable had the original "bullet" connectors on. I used the one with the "male" bullet for the live feed and cut the "female" bullet connector off with approx. 2" cable attached. The off cut is spliced into the indicator live feed wire and has the "female" bullet connector insulated with a soft plastic boot. The other cable has a ring terminal soldered on which is attached to a convenient earth point at each side of the car. Please note that LED's are polarity sensitive and will only work if wired correctly + to + and earth to earth.

Once you're happy with the wiring you can super glue the light unit halves back together, I put a couple of elastic bands round them until the super glue had plenty of time to cure. Once the wires have been extended with the speaker wire, joints soldered and sealed up with the shrink tubing you can refit the lights into the bumper and run the wires up to the indicator behind the headlights. Next turn on the hazard flashers and with your test light trace the live feed to the indicator lights. Now turn the hazards off and part the insulation on the live wire and splice the 2" piece of cable onto it. You will need to insulate this joint with some insulation tape making sure it's sealed tight. Locate the earth terminal on the inner wing and connect the earth ring on the other wire to this point. Make sure all wires are routed neatly out any danger of being trapped or stretched.

The 2 pictures above show the earth points on the inner wings, the one with Grey wire is the O/S and the one with Green wire the N/S.

Once the lights are back in the bumper it's hard to see the LED strips inside them until you turn the indicators on. I hope I haven't missed anything out here, if you have any questions please ask, oh and if you do this mod you do so at your own risk. I think this will be very useful to me when leaving work when the dark nights return later in the year.

Thanks for having a look.

Tony.

One idea sometimes spawns another so it's all good. Let's see the results please. The only problem you may encounter is supporting the centre of the LED strip where the bulb holder would be and you might have to insert something to bridge the gap so to speak.

You could use a bit of plastic strip on the back of the LED to add support. I am sure hobby craft would do a bit in the model section.

bit of plastic strip on the back
That would do the job okay Paul, you would then need some double sided tape (3M) to stick the plastic strip into the light body.

@t-tony can this replace the repeater in the wing panel from an MOT standpoint?
To be perfectly honest Dino, I haven't looked into that but I don't see why not as they're both in the same position on each side of the car. I will see if I can find clarity on this and get back to you.

That would be great tony.
I'm thinking smoothing the new wing panels I have to go on and removing that little side repeater there and using the bumper lights or mounting discreet slim led's under the mirror.

That side repeater says e30 to me (it was a cool detail back in the day when it came out, then they had clear one for the sport model, super cool in the 90's!!).
Has alway looked out of place to me on a car with the lines like a Z. One of the things that says 'parts bin special' just like the door handles...TVR style doors opener a little to big a project for me though!

Hi @Dino D , here is what I've found in the M.O.T. testers manual regarding indicator side repeaters regarding the year after which they are mandatory and also the position of the repeaters on the vehicle,

Vehicles first used on or after 1 April 1986 must be fitted with one side repeater indicator on each side. Instead of a separate lamp, the side repeater might be part of the front direction indicator if it includes a wraparound lens.

Note: The precise position of direction indicators is not part of the inspection, but check visually that the lamps are at about the same height and the same distance from each side of the vehicle.

Lamps incorporating a side repeater are marked either with an ‘E’ mark in a circle or an ‘e’ mark in a rectangle above which is a number 5. (But this doesn't say that the side repeaters have to be "E" marked)

However, some vehicles are fitted with a wraparound lens with no European approval markings. These can be tested by standing approximately 1000mm to the side of the vehicle’s rear bumper with the indicator on. If amber light can be seen coming through the front lens (not a reflection) this is acceptable.

One of the reasons for rejection (failure) is,...."not visible from a reasonable distance" another of the test's vague RFR's.


So if you were to bring me your car with the side repeaters incorporated into the front bumper side marker lights like mine, with the originals deleted, I would have no hesitation in passing it on an M.O.T. test, nor should any other tester. You may need to look into whether they are bright enough to comply with regulations?

Tony.

ps. You can look at the Tester's Manual here, http://www.motuk.co.uk/manual_140.htm

What do you make of these:

I came accross this one eBay, their full website is here: http://www.schroedie.de/en/For-BMW-...W-roundel-badge-LED-lights-Emblem-lights.html

I messaged them for dimensions and these are 74mm by 6mm but they can make up ones to fit other badges. I believe our side roundels are 73mm.

These can be wired to run continuously in one colour and then flash orange when working as an indicator.

Question is can it replace the side repeater altogether?

Looks a lot like the Z4 style roundel repeater only it doesn't protrude so much..
Z4:

Sticks out way to much to be use on our cars as the Z4 has a recess to accommodate.

Ps sorry if this is taking it too far off topic, maybe Gaz can make a new thread?
