I have an amber/ yellow light illuminated just below the amps gauge. LRA13020 What is it ?? Thanks Bob | ||

Hand Brake Light, Thanks | ||

Correct You got it. | ||

Also brake light failure on the early cars if it only illuminates when the pedal is pressed | ||

Good post Martin, I completely forgot about the brake light globe failure feature of these cars. | ||

Robert can test by simply pulling the handbrake out and if the yellow/amber light comes on...bingo, that's it...or conversly pushing the handbrake lever in if the light is illuminated, and if light goes out...again, bingo. The mirco switch may be set (as it is on mine) to illuminate the light with just the first 1/4" or so of travel...too sensitive for my liking, but there it is. Also, the brake warning lights are red, not yellow. In photo below, the yellow arrow is the handbrake light. The red arrow indicates the brake pressure lights. The red light to the immediate right of the handbrake light is the warning flashers, but that is obvious as it is labeled as such.  | ||

Hi Cristian. Martin is referring to the amber light that illuminates when the brake pedal is depressed that indicates a rear brake light globe failure. This is also the handbrake warning light when the handbrake is applied as you correctly stated. Not brake fail lights | ||

Patrik...Oh, now I get it. Never realized that same dash indicator has two functions. Fine print in the manual! | ||
| Patrick Ryan Grand Master Username: patrick_r Post Number: 491 Registered: 4-2016 |
I did read that many years ago Christian, however I did forget this at the start of this thread  Luckily Martin is on the ball. Saying that, I have always wanted to test this function on my car. I guess, break a globe, whack it in and try it?? BTW Christian, Can we see more images of your MPW interior, the dash looks stunning. | ||

Or just take the bulb out.  | ||
| Patrick Ryan Grand Master Username: patrick_r Post Number: 492 Registered: 4-2016 |
Thanks Paul, Ill give it a go. I ran my fuel tank down & emptied my header tank to confirm correct operation of those lights. All was good with them. The fuel tank was particularly interesting when the tank sloshed so di the light. | ||

Modern cars have a delay unit on both the low coolant and low fuel circuits, input has to be on for three seconds before the light is triggered. Did you check your fuel light dims when you turn the side lights on? | ||
| Patrick Ryan Grand Master Username: patrick_r Post Number: 493 Registered: 4-2016 |
Hi Martin. Can't say I noticed that, the fuel light was quite bright and full on, but it was also going on and off as I was traversing a driveway. You seem to have seen this before? | ||
| Martin Taylor Frequent User Username: martin_taylor Post Number: 51 Registered: 7-2013 |
I see my fuel light all the time, these cars use an unbelievable amount of fuel!, the dimmer circuit for the the low fuel light consists of a resistor and a relay so the light doesn't light up the interior at night, could be a little overkill from the RR electrical department. | ||
| Patrick Ryan Grand Master Username: patrick_r Post Number: 494 Registered: 4-2016 |
Martin, Trust Rolls Royce to come up with a light that stays on all the time, but dims it when not required. (I hope I understood this correctly) The wonders of their electrical systems never cease to amaze me. Do you remember Christians issues with seat electrics OMG  I will need to check the light in the pitch black garage one night!!1 | ||

I need to replace a couple of bulbs, and I have almost no light on the dashboard. The bulbs from the tool kit were duds. Now I'm thinking of a total LED upgrade. I found all the bulbs on the web. Is it worth upgrading or is it kosher ? Mike. (Message approved by david_gore) | ||

Mike, You have 2 options: 1. Replace the standard 2W bulbs with 5W bulbs - some improvement but nothing to get excited about. 2. Replace with LED bulbs 5W equivalent or stronger if available - buy one of each wattage available and test to find the best one for your requirements before ordering a full set of replacements plus a few spares just in case. Changing to higher wattage LED bulbs is the best solution. | ||

Gents I have seen some LED upgrades, and the bright white light isn't to my liking. I seem to remember someone saying painting them or a rubber covering will bring them back to the original green hue works well. | ||
| David Gore Moderator Username: david_gore Post Number: 2280 Registered: 4-2003 |
Patrick, The LED's are now becoming available in 3 tones, warm white, daylight and cool white. I suspect the ones you saw may have been cool white as this has a distinct blue tinge which, to my eyes, appears to make the light brighter. | ||

Do not change the alternator warning light to LED, this bulb needs to pass current in both directions to function correctly, an LED will not do this. The rest of the bulbs you can get in many colours, Best to do all or none as they will be different. | ||

Mike Fitting LED lights in my car has transformed the dash illumination. I had great success in painting the LED bulbs with enamel paint. This is useful if any of the blue filters in the gauges are missing, or are so opaque they have to be prized out. As Martin says, do not change the alternator warning bulb. In fact I would not change any of the warning lights as some of the systems depend upon seeing a standard bulb. The coolant level warning system is an example. I have found the illumination of the warning lights is adequate in any case. The problem is with dash panel and gauge illumination. You will lose the panel light dimming facility if you fit LEDs. LEDs of this flavor are either on or off. Hardly a problem on these cars. The following thread has some pics of my painted LEDs should you not be able to find colored ones. http://au.rrforums.net/forum/messages/17002/18929.html Geoff | ||

A lot of sage advice . Thank you. The photographs were a huge help , I'm not mechanical , so pictures really help. I think I forgot to say thank you for the video of the wiper control. (Message approved by david_gore) | ||

THE WAY I ALWAYS TESTED THESE BULB FUNCTIONS ON SERVICE WAS: 1. TURN ON IGNITION-DO NOT START ENGINE- MOVE SELECTOR TO REVERSE OR DRIVE. 2. HOLD KEY OVER TO ENGINE CRANK POSITION, IT WILL NOT CRANK AS IN REVERSE OR DRIVE. 3. BULBS WILL ILLUMINATE. 4. TURN ON SIDE LIGHTS, FUEL LOW BULB SHOULD DIM, SHOWING CORRECT OPERATION. |
