Never heard of them but just looked at their website, looks like serious quality kit. Are you sure it won't scare your series?
 
Hi Rob, you might say that, it is pretty good but I think it is more aimed at the Defender. The H4 Plugs won't go through the headlight bowls and the off-side one looks too short to reach. I think I'm going to have to cut the wires and lengthen them.
 
Made by Red Bison.
Oh and cheaper at Flatdog UK. Seen a few reviews and all seem to be good.

You tend to find a bit of chopping is required on this type of upgrade although I have never tried this actual product. I kind of like the Lucas intermittent headlight design.
 
Can you slip the spades out of the plastic housing to get them through the hole? You could cut / solder / heat shrink the longer bits on but I'm also now making up leads with male spades on to make things longer, still heatshrink over but its easier to change.
Was going to say "why not make the loom yourself?" but having clicked the link that's a keen price for what could take a couple of hours.
 
Definitely going to have to make the wires longer, neither will reach as far as the lights, even if I could get the plugs through the various holes. The beauty of this system is that the original loom is untouched, no cutting required. All you have to do is plug a male plug into one of the existing headlight plugs, plug the new plugs to the lights and tape up the other old plug. That's a lot of plugs but no cutting. I'd rather plug than cut...
 
the ceramic h4 connectors on the Boomslang are removable using a terminal removal tool (or a small flat head screw driver)

the female spades come out of the h4 and it will then pass through headlight bowls no bother.

I've run into this issue doing mine and a mates boomslangs.

Worth while though.

These were on Defenders though? The harness just isn't long enough to reach on a series. Thank you for the reply, good to hear that it is a worthwhile conversion. I just burned out my Lucas dip switch and my main light switch was getting hot so I reckon it's time to get this done, been threatening to do it for years...
 
oh yes absolutely but just to make it clear the connector is removable.

In your case just cut it in half and splice in some extra wire with some solder and heatshrink
 
I fitted one of these to my S3. As has been said, the ceramic plugs need dismantling to get through the bowls (auto correct tried to say bowel :eek:). I don't recall having to extend any wiring.

Works well with new bowls, lamps and H4 bulbs. You can now, almost, see where you are going. :D

Maybe I've got a duff one but it is definitely too short at both ends. If you had had to extend any wires you would sure as hell remember it. Where did you position your relays and did you get a mounting bracket?
Just ordered some wire to do the extending, that's another tenner spent. Paddocks are going to get an email about this!
 
I stuck the relays behind the front panel, I tried to hind then behind the metal work as best I could to hide them from view and road spray I guess. I'll try and get some pictures over the weekend. I seem to remember the wiring round the light fittings being a bit less tidy.

You can see from the pic that one of the leads to the headlight is in no way long enough. I have the relays mounted on the inner wing as near to the headlight as possible and it's still about a foot too short. What is less obvious is that the lead to the other headlight is also about a foot too short as well.
I'm not expecting a dramatic improvement in the lights, they were reasonable before, not good but usable. I am fitting this to take the strain off the switches. The dip switch failed last weekend and I noticed the light switch was getting hot too.
 
Harness fitted. I only had to extend the wires on the OS after all. I found a more direct route for the harness to go and found it was just long enough to reach the NS. I did have to cut both sides plugs off though. It was possible to get the spade terminals out of the plug body but the outer, plastic cover wouldn't let me pull the wires through. Hell of a faff but the lights look brighter, I'll take it out in the dark to confirm.
I have been in touch with the manufacturer, they were sympathetic and will probably alter the harness to suit. They have only fitted it to a lightweight and had no issues; I pointed out that a lightweight is a narrower vehicle... Anyway, I will be in touch with them again, point out a flaw or two and hopefully 'a new improved product' will eventuate.
 
I ended up cutting the rubber plug covers to open the holes up a bit, allowing disassembly of the ceramic plugs.

I'm still not sure why yours wasn't long enough ??

Me neither but it wasn't. I had to extend the wires by about 40cm to reach.
You have rubber covers? Mine are hard yellow plastic. I drilled a hole in the headlamp bowl and fitted garden hose as a grommet/harness covering. I like garden hose, it has so many uses. I have garden hose door seals and numerous places where it serves as a harness covering.
 
Took it out in the dark tonight, lights noticeably brighter. I was surprised that they were so much better, there must have been a lot of resistance in the old switches, no wonder the main switch was getting hot and the dip switch burned out.
Verdict: Headlamp relays, well worth the effort.
