Generally, when looking for harder to find parts such as this signal light my first thought would be to check online retailers like Rockauto, etc. However, this turned out to be a no go as this car has very few parts available probably due to its popularity like you stated. After this I usually hit up eBay just to see what can be found. Interestingly though, ...

Yep, the Bi-Xenon projector units are plug-n-play from a connector point of view - you'd need to buy the units that come with the leveling motor and Xenon control unit as you can't swap the old ones over. The ADL (i.e. "bendy light") functionality doesn't work if you retrofit them (you don't have the necessary control elements on the car side of the ...

The low beam circuit uses dedicated fuses. There are no fusible links in the headlamp circuits. In your case fuse 11 is the passenger side low beam.

Please don't illuminate the road with a flashlight. Flashlights are circularly symmetric. Car headlights are optimized for the road in front, and correctly aligned to not dazzle oncoming drivers. A circularly symmetric light source illuminating the road WILL dazzle oncoming drivers. Any solution to illuminate the road requires high and low beams, with the ...

If any modification is forbidden as you state, then you cannot.

Carefully, and without touching the glass with your fingers.. Also check that the bulbs are inserted correctly. A bulb not located properly into the rear of its headlamp unit will have a very poor and misdirected beam.

It sounds like the dimmer switch is set to off. The car's dash lights are on a dimmer switch. That switch allows you to change the brightness of the lights at night. The switch is capable of switching the lights from full-off to full-on. Also, it is not uncommon for dashboards to have their lights on during the day, while the regular lights are off. This ...

HID bulbs don't dim over time like halogen bulbs simply because they don't have a filament. HID bulbs produce an arc. As a filament deteriorates, it deposits a metallic film inside the bulb. That's what reduces light output. That doesn't happen with HID. HID systems have an ignitor, ballast and bulb. The ignitor generates very high voltage to start the arc....

It really doesn't matter what the package says for color temp because those numbers are usually wrong. Recent testing by the SAE showed that most LED mfgrs color and lumen numbers are way off---no resemblence to reality.

Go to a car spares store. They'll spec the correct bulbs for your vehicle, and they'll also install them for you if it's a quiet day (and they'll know not to touch the bulbs, which would otherwise cause them to blow in short order). If the problem is a fuse or anything else simple, they'll be able to quickly tell you. And they don't charge for this service..

Well, check the fuse box and test the fuses - fuses can fracture so that current won't flow but they still "look" good... Also check the bulbs from both headlights, a multimeter is good for this but putting them across a battery with a wire to finish the circuit also works (be careful not to cause a spark as that can ignite any gas...)...

From a circuit diagram I have found on the internet (if it is correct for your car), it looks like there is a pair of headlight relays in a fuse box under the hood. These relays switch the +12V to the headlights. It looks to me that if one of the relays fails, then the +12 will find its way through all 4 bulbs making them all light when switched to high ...

When I've changed sealed beans for halogens, the connector on the back of the sealed beam was the same as the replacement H4- that was for 5 3/4" round lamps though, other types may vary. Hold the H4 connector in your hand pointing away from you (as if the bulb was plugged in on the other side, with the wires towards you). The vertical pin on the left is ...

My thoughts were: Use a vacuum suction to try and grab it Get a double-sided tape on a wire and try to tape it out and grab it. Use magnets. What I ended up using was a $9 19" flexible magnetic pick-up tool I got from a local Harbor Freight (hardware store). At first I tried to pry out the bulb via the Daytime Driving Lights (DRL) bulb hole, but I kept ...

The best way to see if your headlights are pointing the same direction is to find a wall in a parking lot at night, and with your car facing the wall, drive roughly 25 feet back. You want your car to be perfectly perpendicular to the wall. Place a piece of tape on the wall which marks the center (between drive and passenger) of your car. This should make it ...

If the bulbs are different and I assume HID from what you wrote, then yes there are differences. You will need the HID driver units and possibly associated wiring - which may also need changes or upgrades in the fuse box. There is also usually wiring and control for anti-dazzling to be fitted - if you don’t then it can fail subsequent inspections... Could ...

This sounds like a loose connection. This could be either on the headlamp or at the ground or earth point for that headlamp. There may be individual fuses for the headlamps and that one could have a loose connection.

The same bulb can be used in both head and dipped, what happens is that the bulb filament is positioned precisely within the curved reflector to give the required beam pattern, so the same bulb either does a longer beam pattern for main or a shorter lower one for dipped. Went to amazon for a laugh just to check and it says they are correct for your porsche.....

This sounds like a faulty headlamp relay - replace it and test again.

It will depend on whether your particular car has HID (Xenon) headlights - the reg checker on the Halfords site only operates in terms of broad strokes - pretty much just the barest info (year and top level model). It doesn't include things like options spec so it won't know whether you have the HIDs installed if they were optional on that year's model. ...

If you get the same behaviour on both sides, and you have twin-filament bulbs, then my first suspect would be the switch. If they are separate bulbs then I'd suspect earth connections (as per Mike's comment). We can break the circuit you're testing into several distinct parts: (1) Battery -> (2) wire -> (3) fuse -> (4) wire -> (5) switch -> (6) wire -> (7) ...
