JordanMix, your setup sounds correct.
Pilot Lights are standard BA9s. LSM reports good results with a very bright LED unit for those at
http://www.ultraleds.co.uk/wide-angled-high-power-bulb-xenon-white-p-1645.htmlI just used 6LED whites. They are brighter than stock and look good (not too directional) But maybe my next upgrade will be to a pair of LSM's bulbs.. they look extremely bright!
Flasher unit is: CF12ANL-01. Works great and can handle 10A so you can run a million or so LED's off this unit
. Downside... no clicking noise. But I recommend an LED electronic flasher over using the standard flasher plus resistors... whenever you add resistance, you are just increasing the current draw in the circuit, which takes you back to the old problem, the RE alternator can only handle so much load.
The "experts" recommend using the same LED color as whatever the lamp lens color is... so amber for amber, white for white, etc. A light in the same spectrum as the lens will pass as much if not more light than a white light that is technically brighter, for this reason. So you are *probably* better off with a blue light for your neutral finder... but I couldn't be bothered, and just bought standard whites and a couple of extras... that way I have interchangeable spares for all my display bulbs. They are plenty bright and a big improvement over stock.
However, as LEDs get brighter (the super high efficiency units) the amount of heat they generate rises exponentially... a Luxeon 5w tail light has its own heat sink as a result. I recommend avoiding the ultra-high efficieny ones; I ended up returning all of them as the electronics are touchy, they can be shortcircuited (and destroyed) easily and they overheat. So what worked for me was a large array of the 5mm regular LED's in the tail lights and turn signals (72 in the taillight, 36 in the turn signals). They generate zero heat, are very very durable (the whole thing is encased in a plastic dip) are very bright in large numbers, and you can switch polarity or shortcircuit the connection without damaging them in any way.
One thing to be careful of when buying multiLED BA9s and 1156s and 1157s... If you buy a multiLED bulb unit with too many LED's they may not fit in the stock housing. I purchased some 57 LED 1156 bulbs for turn signals, and they are too TALL to fit in the housing. So read the dimensions carefully.
Lastly - your first question - to replace a brake/tail light with an LED cluster, just make sure that it is an 1157, two-stage LED cluster, with a low and a high intensity circuit. That way it will run off your standard bulb holder and work in exactly the same way as your existing bulb. So you want a dual element or dual intensity 1157 bulb for your taillight/brake housing. You can buy a 3 or 5w luxeon 1157 bulb (1157-xLX3 - 76/270ma - 30/85 Lumens or 1157-xLX5 - 62/335ma - 20/134 Lumens) and drop it right in. I tried that and none of them worked properly (because in my taillight housing, the metal "tongues" that connect to the bulb are somewhat loose, and shortcircuited the bulbs). Other 15, 21 and 36 LED bulbs tested by others were not as bright as stock. So instead I ended up making my own, using two 36LED dual-intensity bulbs (1157-PCB-R36 Red LED lamps) and chose the wide, not the narrow angle bulb. Then I soldered the two bulbs to a single 1157 connection, adding a single downfiring white WLED-WHP LED Wedge Base Bulb. I chose the wedge simply because it has two exposed wires for connectors, which you can easily solder to. (With this bulb, however, you MUST get the polarity right, so test before final soldering) Then I hotglued it all together, backed with some white plastic stock to keep it square in the taillight housing. This all may sound complicated, but actually took only half an hour and has worked perfectcly ever since. It's MUCH brighter than stock and draws far less power.
P.S., superbrightleds.com states you can join PCB-W36's together (although it voids the warranty). YOU CANNOT join the PCB-CWHP9 high power units the same way, as there is circuitry in the 1157 base.
