Extra Light, part III

Image
TL;DR Pimpin' ain't easy Read part I   and part II for the full PIAA story. Even I think that a third post about those additional lights is a bit much. Yet again, the time spent 'researching' and fiddling with the adjustment make it worth my time writing it down. This whole blog could have been a collection of Post-It notes in Google Keep, all bullet points, sketches and figures. Anywho, as pleased as I was to transform my Seven into a light ball, it was too much and a plain nuisance to others if we're honest. Flooding the scenery up to the roof of houses with pissy yellow light wouldn't bring anything useful in actual fog either. The fact that the white drive beams were aiming too high was not as problematic, but the goal was for them to fill the black void left when the low beams turn off as the high beams are activated. I got a first check on the wall of the parking lot at work at the end of the day, with evidence recorded by the dashcam for later analy...

Extra Light, part II

TL;DR The easy way, stealthy enough This is a follow-up from the previous post about adding PIAA LPW530 lights to my Caterham. Alignment is described at length here . With the car on hand, it took a whole 10 seconds and a wooden skewer to understand that the PIAAs wouldn't fit between the grille and the radiator. The space there is about 1 or 2 cm short. Change of plan then. I considered fitting a bracket down from the large nut where the headlight bowls and indicator pods are attached. It looked like a real chore of a project, and I didn't want to mess up with the headlights alignment. After much reflection, weighing various pros and cons, I went the easy way with a standard bracket made for that very purpose : a motorcycle clamp for 22-28mm tubes, made of cast aluminium. I was worried about adding unsuspended weight (~500g on each side) and about vibrations. I reckon that being about 1/3rd of the way out, it should be like 150g extra, which is close to what I've saved wi...

TL;DR Adding weight and complexity See them installed and in action here : part II    and finally part III about the alignment To quote Ben Jabituya in Short Circuit : "You know what many people are liking at night ? Headlights." Confession time. I'm one of those people he was talking about. Since the Vosges trip in August and the driving-mountain-roads-at-night-under-the-rain that came with it, I've been on the lookout for additional front lights for the 170. The issue comes from the void created near field when the main beams are switched on. With the original halogen headlights, you can hold the flasher button down to force both beams to illuminate at the same time. Replacement LED H4 bulbs didn't allow for that, but the illumination remained satisfactory. The proper LED headlights on the other hand alternate between two sharply defined beams that don't really crossover. The only Caterham with additional lights I know about is from Gilles in France. He l...
