Tr7 headlight bulb

[Dsr]

Tonight the headlight bulb has blow on my tr7,how do I change it?

 

Do I pop the lights up then disconnect the battery? Or go in from underneath?

 

Is there an easier way?

[Steve.M]

Wind the motor up manually with the battery disconnected. Turn the actuator on the end of the motor anti clockwise. Or raise the unit and disconnect the battery!

Thank you for replying Steve, very helpful, I'll give it a go

One other thing, the bulbs that are in there are original,

So it's like driving with a couple of candles!

 

Can I replace them with halogen bulbs, or will the wiring not take it

Whatever you do - take extreme care with this one!

 

If you manualy raise the headlights never try doing this with a power supply attached - the stickers within the bonnet area advise disconnecting the "Red" plugs at the rear of the light unit - failure to do this could mean that the motor will run and damage to yourself or the vehicle could occour (these motors have loads of torque)

 

1, Once you have raised the headlights disconnect the battery

2, remove the black rubber light surround (philips screws - hopefully not stuck!)

3, undo and remove the chrome ring holding the lamp unit and change bulb.

 

replacement is the reverse order of above, however whilst you are looking at things in this area its worth spraying some grease at the hinge mechanism and making sure the connections are clean and not corroded within the red and white electrical connectors behind the lights and within the bonnet area.

 

The black rubber surrounds are held on with philips screws which pull up on metal washers which are bonded to the rubber - sometimes these break free - they can be reattached successfully using a hot glue gun or a good rubber bonding adhesive. it is worth putting the screws back with a touch of copper ease to make sure they can be un-done next time.

 

You should have no problems changing your original sealed units to Halogen bulbs - units are always available from the usual suppliers. I have never had worries about overloading the wiring system and have at times used 100W halogens - normal 55W halogens are very adequate for normal driving. Some people have made changes to the wiring loom to add in extra relays etc, but as with anything electrical the system is only good when connections are clean and the full current is allowed to flow!

 

 

Hope this helps

 

Cheers

Brilliant, thank you very very much Ian!

 

I've only had the Tr7 for just over a year, so still finding my way around it,

 

Thanks again
