I have not seen the ones that you describe, & show, but i have used Hella inserts for many years. They're not cheap, but they ARE good.
As you well know, any headlight upgrade in these little Datsuns should be a two part deal, as in
1. Fit a relay system. This will perk up even stock lights.
2. Fit whichever headlights you wish.

If done in this order, all will be a source of joy. If not, it'l be tears before bedtime from dissapointment. This upgrade is money well spent.

I agree definitely go with a relay. Mine was equipped from the factory with one but my El Camino wasn't and when I added one it was an incredible difference.

Any idea where to get those crystal clear units in the US?

I see them on Ebay quite often for really cheap. They also have provisions for parking lights. I can't vouch for the quality of those units though. Unfortunately the Raybrig ones are designed for driving on the left otherwise I could send you a set. Here's a link for some but they look to be Japanese market units so the beam would probably be wrong??:

There's a ton more just search for diamond cut. These are way cheaper than they're available here.

arite it was really bad not using relays with these 100watt lamps as i had a few difficulties in the fuse area with blown fuses and the cable frying on the back of the fuse box. i went back to 55/60 globes until it had 2 relays put in. had it done in orange nsw for $70 ! included 2 new relays, 1 cut off switch, 1 30amp fuse and all the labour / cabling.

use relays ! now it is awesome. id say these 100/55 H4 lamps are at least 70% better (brighter) on high beam that 55/60 H4 lamps.



as for the LED's - ive found lots of very nice looking LED lights avail at Jaycar(.com.au) which im going to put onto the 1200 in due time. ill prolly post an article on it if they are better than normal blinker and parking lights. on new Jaguar's etc which use LED's, the lights look amazingly clear and bright. also they will probably never need to be replaced again if you change to LED's.

i wanna get mew lights, mine are really dim

Will you still need a relay if you only use 55/60W H4's ?

anb008 a relay isn't required for only 55/60w globes, but it will help alot. This is because the relay bypasses the switch and sends power straight to the lights. Since the switch is a few years old now its contacts will be warn and be causing resistance to the power flow to the lights. Its agood idea to put new earths on each light also.
Every bit helps to make the lights work their best.

i can vouch for the NARVA kit it is great i have it on my 120Y. but i have no relay what does the relay do to improve the lighting? i also have a set of Narva driving light i plan on putting in the small light pods on my grille, they came with a relay in the box. you see on new cars where the relays plug in, can you buy the plug plates unmarked so you can make your own similar to the Blade fuse conversion for old glass fuse boxes?

I personally recomend a relay on even a stock vehicle.

I place the relay near the radiator on the front panel if room allows & i use a spade terminal in the old headlight plug to provide power to the switching side of the relay. I then run a nice heavy duty cable from the starter terminal so as to get full battery power from within the engine bay to the relay. It's a good idea to mount the relay on the same side as the starter to minimise cable length & simplify the wiring.

You now only need to make up a new harness with new plugs for the bulbs to make it all work. You would be amazed just how much this will improve even boring old sealed beams, which should be discarded in favor of QH types as soon as the amazement subsides. Make absolutely sure that your earth connections are good & have cabling at least as heavy as the largest feed line to the bulb.

Make sure that the beam is correctly adjusted so as not to bring a dose of road rage down upon your head.

I did this to my son's 120Y with 55/60's & you could swear it was like driving behind a searchlight,............ almost.
