Talk Morgan Forums Community The Malvern Arms LED sidelights upgrade

I want to replace the filament bulbs on my sidelights, rear tail and brake lights with LEDS. (No change to the headlights.)
Will these replacement LEDs be allowed under MOT rules?

If you search there are three or four comprehensive threads on fitting LED lights giving excellent recommendations on solutions.

I think the only time MOT legality cropped up is fitting bright LED Daylight Running Lights (DRL) bright bulbs into side or wing mounted side lights. The MOT issue was do the DRL have to dim when headlights are dipped? I checked on DVLA web sight and concluded they "do have to dim where dipped headlights on".

I found a DRL voltage sensor relay which in addition to DRL + and - feeds to DRLs also had an input line from the dipped headlight feed and, as soon as dipped headlight selected the DRL got half voltage.

I have just completed my DRL installation in wing mounted bullet lights by disconnecting lights from side light circuit and connecting to Radio feed so as soon as position 1 on ignition key selected DRLs come on. The DRL feeds go through relay to wing lights.

The DRL relay worked but I have to say the amount of DRL dimming was marginal but noticeable.

That said my car goes in for MOT on Wednesday so I will find out if it is acceptable!!. Keep you posted

The later Roadsters have side light & rear lights coming on with the ignition so the DLR rules don't apply as the rears are on.
I also hard wired my S1 Roadster so the side & rear were on with 1/2 moon leds in the headlights. That passed many MOTs & although not E marked made 2 trips to the EU driving down to the Italian lakes & Sorrento.

Just replaced mine with LED equivalents from Classic Car LED's. Duncan is the contact there who will talk you through your needs. The link takes you to the red dual intensity stop/tail lights which are a simple exchange for OE filament bulbs. It's recommended if you use clear or retain the red lens, that you order the red LED version.

I have LED bulbs in all minor lights except turn indicators and my Mog passed its MOT last month.

Sailed through the MOT with the new DRL wing bullet lights that dim when dipped main beam is selected. I didn't ask the technician whether it was mandatory.

Shouldn't this thread be in the tech section? (Or is that thread drift ).
