Hi, hope you folks can help.  I'm looking to get a bit brighter bulbs for our two CitiGos but keep coming across conflicting info about what size I need and I want to get it right before ordering.  Both are 67 plate, one is a colour edition and the other a SE.  Anyone know for definite or how I could find out.  I've tried all the websites putting in reg no etc and most say H4 but some say H7.  🤷‍♀️

 

Thanks for any help you can give.  Also open to any opinions on bulbs 😊

Osram Nightbreakers every time, all night long.

 

As for fitting,it may be that the one car has H4, and the other H7. The only way to know for sure is to take a bulb out and look.

Thanks, those were one of the bulbs I was looking at, fed up of trying to drive with the original ones.  

 

I suspected I might have to take them out to see but I'm worried if I break one (or two) then we are stuffed and unable to use the car until the new ones arrive.  Not much in the way of daylight at the moment!

If you have one bulb that does dipped and main beam, you need H4. If you have separate bulbs for dipped and main, it's not H4.

Thank you Chris, I'll check that out 😊

Twin lights are fitted to each lamp unit in some higher-spec models. These use a pair of single filament H7's each.

All other models use a single twin-filament H4 in each lamp unit. It's easy to tell which are single or twin by looking at the lamp unit from the  front (meaning you don't even have to open the bonnet!)

Nightbreakers are good, but as has been well-documented, they have comparatively shorter lives. This is the same for all brands of extra-high brightness filament bulbs, as the filaments are under a lot more stress.

Thanks Steve, much appreciated.  There are definitely two bulbs (in the Colour edition anyway). My son is out with the other one so I'll check it later/tomorrow and then get ordering.  I'm aware of the faster burn out but to be fair, neither car does many miles so wont be as impactive as it otherwise might.  The cars are both 67 plates and the one I mainly use has 8k on it and the other about 14k.  One of my son's uses this mostly and he takes it away to Uni even further north with less daylight.  He has the benefit of young eyes but he has to drive on unlit NSL roads regularly.  I think the plan is to replace the bulbs in both but keep some more basic (aka cheaper) bulbs in the glovebox for emergencies.

So I have my H& bulbs, replacing the ones in my son's car first as he's heading back to Uni tomorrow,  Got one changed without too much bother but the other one was a bother to get out and now It won't clip back in, gahhh.  Any tips?  There seems to be no decent youtube videos unfortunately.

 

If all else fails, I'm going to have to see if the garage is free early tomorrow to do it for me.  Can't obviously take it anywhere until it's light 🥵

Which bulbs do you have?

Where are you in the UK?

 

Thanks, AG Falco

Sorry, it's H7 bulbs, didn't realise I'd hit the shift key.  And yes, in the UK.

I'm in Stirling, Scotland.

Look here for info:- 

Thanks. AG Falco

Sorry for the late reply, I've only just seen this.  The adrenaline of having to take it to the garage first thing in the morning so that my son could travel back to Uni took a while to wear off! 😁

 

Was it wrong to feel a bit vindicated when my very experienced mechanic also seemed to be having bother with it?  Anyway, he nipped into the office to get something and the young lad mechanic strolled over and fiddled for about 5 seconds and popped it in.  The lovely guys didn't even charge me.  They know I'm going back for all my service needs. 

 

Thanks very much for the linked info.  I still have the new bulbs for my own car sitting waiting to be put in, I might pass them in when it goes in for it's service

 

 

Read somewhere H4 has 3 connections, H7 has 2 connections.

yes, because the H4 is twin filament.

The H7 is a single and fits Citigos with the excellent twin-lamp headlight units (i.e 4x H7 is total)
