"Brake Lamp" light/resistors question... - Honda Prelude Forum

Slatelude · 07-05-2007, 09:28 PM

OK, so I'm working on finalizing the new LED tails (ooh, thats a tease eh?). And of course the resistance of the LEDs isnt correct so my BRAKE LAMP pops on. I need opinions and insight on either:

A: how to wire in resistors to make it think that the stock lights are OkeeDokee....or

B: what wire going into the sensor (mounted on the white part that holds the tail bulbs) sends this signal and is there a way to bypass it.

I'm new with this whole resistors thing so if you need Ohms, Volts, Watts or whatever off the LEDs to help me figure what resistors I need then let me know. Help?!?!?

i wanna learn about the whole LED thing, i'd like to fix me a set of tail lights for the lude. i just can't seem to find any that tickle my fancy!

mine look completely stock, just with 8 bulb LED in the running/brake, and 4 bulb in the turn signal, left the reverse stock. I'll try to get a comparison pic of the LED vs stock this evening (thats when it really makes a difference).

I got a set of "Spiderlites" LEDs for my tails and it also set off the "Brake Lamp" on the dash. A friend who is a Honda tech told me that if the new bulbs aren't EXACTLY the same draw as the stock bulbs (or replacements of same type) that the light will keep tripping the sensor. They told me I'll just have to live with it or block off the dash light, since they can't legally do it for me.

I know when you use LED's as turn signals you need some kind of in-line resistor since they flash independently of the brake lights, but mine were replacing the brake lights only, so it shouldn't be needed in my case.

I ended up just removing the dash facing on my '92 and blocking the "BRAKE" lamp off- it drove me crazy otherwise.

We are professtional led auto bulbs ( direction ,tailing lamp ) .manufacturer locate in shenzhen ,china .

Nowadays led has spread very quickly in every corner ,such as household ,showroom ,hotel ,entertainment ,etc .And in car ,after first led bulb used in Audi car ,it spread also quick in car lighting .

Lux led lighting dedicate himself in Household bulbs & autobulbs ....

1. Household bulbs ( MR16 3*1W (Luxeon chip ,50-60Lumens/W .equivalent 60-75w incandescent bulbs .GU10 .JDRE27 ,E14,PAR20,PAR30,PAR38 bulb for choice .When use 90-100Lumens/W WeiTian chip ,it can substitute 90-100W incandescent bulbs .

2.Auto car lighting : Festoon 33mm ,37mm ,42mm ,We set low current when in 12V .and protect circuit .because once car voltage increase to 14v .it will easy run to full current even exceed it .and led will easy go die .

3 .Led project lamps : point lamp ,wall washer ,underground lamps .

Also choice of led is an important process .

if further interests in these products ,kindly send us an e-mail and tell us .

Best regards

Get a digital multimeter, meter the resitance (ohms) of a regular bulb, then meter the led replacement that you have. Simple math will tell you what ohm value of resistor(s) you will need.
